I saw Luminodot on a Japanese TV programme, where a young idol was handing a board with a luminous Mount Fuji to Jodie Foster. At the beginning I wasn’t really impressed, maybe it was Jodie Foster’s skeptical face or the Fuji itself. But I looked for this gadget in the toy shop and when I had it in my hands I realized that actually it’s not just a more technological version of the white coloured plastic pegs sticking board.
The 70×50 grid can accomodate 3,500 light pegs and it has a programmable backlight animation function which add some more fun. On Luminodot you can find many templates and examples (unfortunately only in Japanese).
