JELLIFISH is a unique, liquid-like, intuitive thermostat UI, following a simple rule - up is hot and down is cold. The "desired temperature" bubble simply follows your finger everywhere on the screen, while the background color shows the actual temperature, by following again a simple chromatic rule - red is hot and blue is cold. No numeric degrees, no bull - just the bare minimum - the only thing we actually need. I have lead and completed this project as part of an Advanced Design Program. Final product - fully workable prototype.
