Ian, Congratulations on pursuing this fantastic design concept. I remember meeting you and seeing your design at your degree show, and I am so pleased to randomly come across it again on this website. A beautifully executed product which engages with its user in a fun yet sophisticated way. A product I would love to own.

low power LEDs, the small 5mm round ones, dont produce any noticeable heat when only drawing 20mA. With about 3.3V that is only about .066 Watts.
But the new high power are 1W, 3W, or 5W LEDs and they do produce a lot of heat. That is why they have heat sinks.

LEDs by nature are more efficient than incandescent bulbs, but that doesnt mean they dont generate heat. They do produce more light per watt than incandescent but if you put 1 or 3 watts of power through a tiny 5mm piece of electronics you are going to make it hot.

In the concept above, and by looking at the photos I would guess the designer indended to use low power 5mm LEDs so heat would not be an issue. But you also dont get much light from it. It would look mostly like a mood light or night light.
