Because I'm so easily distracted, I love silly USB gadgets but they tend to wear out their welcome after a few minutes. I think, though, I could learn to love Tengu. Tengu is a little USB-powered device that responds to voice and music, and while this is the standard modus operandi of most useless USB gadgets, Tengu can actually lip-synch to music or your voice. Not perfectly, of course, but based on videos, enough to be thoroughly amusing for a little while.

Here's one demo:

Tengu changes its expression if you blow on its um, "face". This is probably going to be lots of fun when I want to pretend that I'm having a conversation with someone who agrees with me completely.

Tengu is $48 from Compact-Impact. Via Chip chick.
