Fun Fact
When “GIF” was named word of the year in 2012, Oxford Dictionaries U.S.A. credited Tumblr for pushing the word.

light reflections and light refractions through the thermoforming shape

Production of the thermoforming form
a layer of resin closes the pores and makes the inner surface smoother
small holes ensure that the mould is vacuum formed at all dents

final electronics
after a very intensive excursion into the world of LEDs i was able to build up a circuit which allows me to adjust the LED (2700K warm white) intensity in advance.

little research regarding the price.
portable LED-battery operated lights usually cost around 80-150 €. exceptions in high quality materials (metal) also twice as much.
fixed bathroom lamps made of glass vary in price. 50-600€, up no limit. the main part is a big part around 200€.
I still think that a realistic price for my specific bathroom atmosphere lamp is in the range of 100-130€. although I would find it cool to buy it around 80€.

quick update for the 3D file:
the total hight of the cylinder is 50mm and the diameter is 73mm.
(the previous model with the wrong pcb/led was 65mm high and 90mm wide)

In order to achieve an atmosphere and the impression of the water surface in the glass, I have provided the form, which is thermoformed, with slight dents, so that different material thicknesses and wavy structures appear on the surface.

Shape of the glass. I have collected pebbles at the lake and used them as an aid to better shape the form of my glass. The first styrofoam prototypes were very large, therefore hardly tangible with one hand. The first thermoformed model on the other hand was perceived as too small so that the lamp was too inconspicuous/shy. The mdf model in the picture is the new prototype, which is slightly larger than the thermoformed model. The organic shape is derived from an elongated triangle and the more detailed eye on the rounded pebbles.

Electronics. In the previous prototype, i installed a pcb board from another light with leds, usb hub and lipo battery. But because the board is so big and the leds don't create the right atmosphere, I started looking for a led that fits my concept. After a long journey and research i was able to find different small cob-leds (3000k and 2700k with 9V and 12V), 3.7V and 7.4V lipo batteries, adjustable step-up voltage devices (4-12V and 9-30V) and separate usb hubs on the internet at different suppliers. the components are much smaller than the one i used. They also have a different light mood (warm-white). It allows me to build a smaller casing, which is in line with my concept and harmonizes proportionally. Due to the new components the lamp comes to its true potential - hopefully

Drop
Is a handy bathroom lamp that can be attached to any smooth surface (such as tiles, glass, door) thanks to a suction cup.
The glass shape protects the integrated battery-powered LED bulb from water or moisture and creates a warm cosy atmosphere due its wavy surface.
To charge the lamp, move the lever to the side, this will release the suction cup mechanism and the concealed USB port is accessible.
_____
In addition to the direct name, the shape of the glass can also provoke the association of a drop.
The free organic shape also allows other associations which are related to the topic of water, such as pebbles, rounded by water.
One can formally recognize a drop, as well as the fact that a drop "sticks" to the wall - like the suction cup.
The transparent glass with its wavy surface supports the connection to a drop.
The refracted light will also create a shadow and reflection play on the wall that resembles that of water.

Thanks to the midterm presentation, it turned out that the relationship between the design and the bathroom was still not sufficiently recognizable for people.
The design was not yet precise enough in terms of its location and associated constrains/limitations.
For this reason I have refined the design again.
The atmosphere that the light creates can remain as it is. It is received as warm and cosy - like a candle.
It was incomprehensible where the light is located. A version that could stand on a laundry basket or a bathroom stool for instance, was considered unrealistic/blurry.
A wall lamp has been accepted more, but it has been said that it is a very clear decision- if someone has to drill into the wall/tiles- to fix a lamp.
For this reason I decided to go back to my intuitive fixing idea of using a suction cup (big one - known from GPS systems in cars). This creates a direct reference to a smooth surface, as are the bathroom tiles. It also makes it possible to change the position of the lamp - as the customer can mentally imagine it.
The motion sensor could be in the lower part of the lamp. It would be rotatable to be aligned in all directions.
The lamp body could be formally directly related to the candle. (radical straight cylinder), the lamp would take up less space and appear less intrusive. Thus the form embodies the light in a different way than the big organic one.
Also it might be better to make the material more robust (plastic) to make it less fragile than glass. Or I use borosilicate glass, which is very stable.
The entire housing must be waterproof and moisture-proof.

final model for mid-terms.
the glassblower assured me that an oval shape would be possible to made, with a plaster mould.
the inward-rotating element at the foot of the led, however, takes more time to produce. so the feedback from the glassblower was to cut this part straight, so that the glass mould consists of pure convex shapes.
A rubber sealing ring at the opening can protect the led from moisture.

illustration of the wall and table version.
the table version should embody stability and be more down to earth.
the wall version should embody lightness and have filigree elements.

thermoformed lampshade with turned wooden leg
the legs could be protected by a varnish/lacquer or could be made out of other materials for instance ceramic.

On the one hand I try to find a formal language that picks up the light of the LED and enlarges/scatters it. On the other hand, the light should embody the intimate, introverted, candle-like light.
At the moment the organic form is not yet finished, as it is neither underlain by a hidden geometry nor does it really flow freely organically.
Structures could create a very interesting contrast between the technical LED and the natural glass. This would also result in much more emotional light reflections, refractions and shadows.

Sketch Session
I was supposed to embody the light by doing sketches.
I tried to treat the material fairly, to observe the manufacturing process, to embody the light of the candle and consider the location.
I keep noticing that I have to know the limits, or rather the rules, of the production, the material and the location before I can visualize forms or play with my creativity !
