That’s pretty neat use of a LED matrix. I might see about doing something like that myself. I currently have a 8×8 bicolor LED matrix hooked up to an AVR, so far I’ve written a simple pong game.

Looking at the breadboards, I don’t see any bypass caps. Maybe he could get away with USB power if he threw 100uF across the bus bars of each board and .1uF near Vdd/Vss on the chips.

first time i heard of tengu and this is something i’ve been wanting for years now.. the clone lacks the “bling” original has, (probably due to designers being involved in the original and all) and both can use a little more fine tuning of responses but overall, this is the coolest “world can do without” item i’ve ever seen..

p.s. i actually considered buying a tengu but the website is completely in japanese with no english preference and my link reading skills were only so much..
