For context, this guy has:
Built a Marble-powered music machine (you've probably seen that video)
Decided to completely redesign it from the ground up half a year later because the original wasn't good enough to go on Tour with.
Called it the Marble Machine 2.
Got about 7/8ths the way through designing that one, gave up and started from scratch again.
"Marble machine X".
Got that almost 80% done as a final project.
Fans pick up and complete the Mable Machine 2 design.
Meanwhile
GUESS WHAT, STARTED AGAIN
OVER 30K MARBLES PLAYED TO WITHIN 20 MILLISECONDS CONSISTENTLY WASN'T GOOD ENOUGH
"Dumb Design requirements are holding the Marble Machine X back from Success, lets see if we can at least try to learn something from my biggest mistakes :)"
YOU ARE ASKING FOR A DESIGN THAT DOESN'T DROP A SINGLE MARBLE IN A MILLION TRIES, NOT AN EXAGGERATION
STOP LOOKING UP TO ELON MUSK AND GIVE YOURSELF A BREAK
Started a new machine from scratch AGAIN, called Marble machine X-T
Drags through the final construction of the Marble machine X because over 10k people are paying him on patreon with the promise of the MMX.
Now the dude's making a device to measure gravity to make marble drops more consistent. Instead of just making a felt catching tray underneath for the 1 in 40 THOUSAND marble that falls out.

W1 design is done finally!!
W1 is both of the V models having combined themselves into one machine! Here are some notes on it! There's a lot to this fucker I think, but I'll do my best to cover what's most important.
Design notes:
More fragile areas are usually using V2's standard tougher plating. Main examples are the base of it's limbs, as the less of it's arm it potentially loses the better, it's head (which has 2 brains inside!), kneecaps and it's shooter arms, which are less powerful but made to handle guns and weaponry with more finesse.
Note! The knuckleblaster largely is off-colored, because it is a creation of V2's before their merge (she was not made with it). She made it before they combined. Has modified only it's hand after their merge (blue).
Big surface areas or places where blood often ends up use V1's plating. So like it's chest, forearms, punching fists and so on!
Their eye looks like that, because it's cool. and. 2 brains.
Their wings are a combination, because of limited resources. If it could use all of V2's it would as they are better protected.
Character/lore notes:
The V's do NOT fight for the body. Actually any disagreement on actions it must perform are VERY dangerous and scary they prioritize reaching a solution as FAST as possible.
Not functioning correctly can mean death. That being said differing opinions specifically are okay as long as they reach the same final conclusion on what to do. Nobody is panicking if they disagree on what their fave color is.
The two brains send requests incredibly fast between each other to operate the body. Both have full control over the body and must operate it together. This is a VERY processing heavy task and an inefficient one so it requires a lot of blood. It is a VERY hungry machine.
W1 combines before the events of the game! W1 would go through the events of the game in place of just V1.

bro did boeing design this spaceship why is EVERYTHING broken???
fanart OFFICIAL COVER ART for time to orbit: unknown by @derinthescarletpescatarian
god the attention to detail and creativity put into the futuristic technology is astounding. my favourite detail is how the ship creates artificial gravity through centrifugal force. (get inside the Giant Washing Machine future space colonists! it's perfectly safe and very functional!)
design notes:
I'm only on chapter 6 rn but this is what aspen looks like in my head.
the vibe im going for is borderline cosmic horror. aspen greaves' face opens up to reveal Spaceship Guts inside. i decided to combine aspen with the s.s. courageous to make them one organism (Courageous-Aspen) to symbolise how the colonists' survival are totally dependant on their malfunctioning ship. it's also a cool way to show the weight of loneliness and responsibility weighing on aspen e.g. the ship is constantly on their mind, even as they're barely holding themself together.
mini!aspen is on a spacewalk looking at big!aspen. something something, existential angst about realising how vulnerable and insignificant you are in the vast uncaring void of space.
Wips:
not a lot of revisions between draft and lineart. my only big change was making the aspen's eyelines match up, so they are looking at themselves. oh fun fact! the plain black background was actually a merging error, i originally had stars but the layers got deleted and i ended up keeping it like that because it looks SO cool and bleak.

Humans and their pets
The sentient races of the universe have just about started to get their heads, or approximate similar in function body parts, around the odd nature of humans but only recently have humans begun to bring other Earth creatures into space with them.
“Don't worry about Fluffy, he's totally ship trained.” the human designated Bradley spoke with frightening casualness about the creature sat at his side. It's muzzle was level with his hips and it's forward facing eyes showed it had predator history just as much as humans did.
“It has fangs.” Captain Mota'tog was unimpressed. The permissions were correctly stamped on the file and yet such a creature hardly appeared inoffensive.
“He does not, he's not poisonous. Of course some of his teeth are sharp, he's an omnivore.”
“He's a hunter.”
“He mostly hunts biscuits. He'll scavenge in the canteen from anyone soft enough to feed him. He's a certified well-being dog. People stroke him, he's got really soft fur, it makes them feel better. Look, he's wagging his tail, it means he likes you.”
Mota-tog whistled uncertainly.
“Oh wow!” One of the human engineers arrived at the airlock and dropped her bag as she stared at the dog. “So cute!”
Fluffy jumped round, tail wagging furiously, nuzzling in as the woman buried her hands in his warm soft fur.
“You are totally gorgeous. You're so fluffy and beautiful, you're like a little polar bear. You're here to stay, yes you are.” the woman happily baby talked to the dog who was more than half her size.
Bradley looked at the Captain and indicated. “See. Dogs make us happy.”
“You do all the care for it.”
“Of course.”
There were some false starts with the rest of the crew who were not so trusting of the huge pack hunter in their midst, but over the next few months they slowly learned to trust that the worst he would do was beg for food off their plates at meal times. Some of the braver aliens even began to pet him.
Then an alarm sounded.
Everyone raced to their emergency stations.
Bradley was in the cargo hold, his duty was to check the cargo was safe and secure.
He had quickly trained Fluffy to sit in a corner out of the way. It kept him safe in case anything shifted. The last thing he wanted was for his pet to get hurt by moving cargo.
The clang of magnetic grabs was deafening.
The alert was for a boarding raid.
Pirates.
Bradley cracked his knuckles and picked up a pry bar.
Through the rest of the ship there were varying degrees of panic.
A few of the other species could fight but most looked to the humans, having learned the way they fought when cornered and knowing their best hope to survive was to stay back and wait for the screaming to stop.
“What the fuck is that?!” the shout was shock and outrage. More anger than fear in the moment.
Crouching as it came through the main airlock was a creature taller and broader than anything else on the ship.
“Star spirits preserve us,” Mota'tog whistled. “A Batath.”
“It's a bloody troll is what it is.” Martins snapped.
Everyone froze as they heard the snarling and growling.
It was not coming from the Batath.
Fluffy arrived at speed and leapt, not caring can his opponent was huge. His fur was already matted with the blood of pirates and this was just another opponent.
The humans charged.
The Batath could only concentrate on one enemy at a time, it was used to picking off creatures as they ran, not fighting them off as something had its teeth deep around a knee trying to rip it apart.
The pirates ran when the Batath fell and the gore covered humans turned to face them.
Bradley let himself drop to the deck. “Don't worry, I'm fine. Good boy, Fluffy.”
Mota'tog shook his feathers as he watched the dog go back from snarling killing machine to placid fuss receiver. “I swear to the spirits, all Earth creatures are insane.”
