three models: two fifty six (16×16), one twenty eight (16×8), and sixty four (8×8). each is a reconfigurable grid of backlit keypads which connects to a computer. interaction between the keys and lights is determined by the application running on the computer. there is no hard-wired functionality.

I am really looking forward to get one od those. If anyone wants to sell his 8x8 version, please drop me a mail. Currently only the DIY-Kits of the 40h version are available again, everything else is sold out. I think i will get myself one, stay tuned for a detailed review when i got it.
