Cool, geeky and $18: MP3 Retro Speaker amp (off-topic)

This is completely unrelated to photography, but we just saw this online, and it looks so cool, we had to mention it! It is an MP3 Retro Speaker Amp offered by ThinkGeek for $18 plus shipping and handling. It is powered by either USB or three AAA batteries.

We do not have this item, so we can't tell you how well it performs, but we found a couple of mini-reviews at The Gadget Site blog and firebox.com.
