Ask HN: What's the geekiest toy you bought for under 10 dollars

Haven't bought one yet, but I really want to get a Rite in the Rain pocket notebook for $4.25 and see if the legends are true / how much water damage it can stand.

http://www.riteintherain.com/. They make waterproof paper. So cool.

Probably one of The Cubes playsets: http://www.amazon.com/The-Cubes-CUBES-Copy-Center/dp/B000BJF...

There's a few "departments" that fall in the sub $10 range.

Got original Gyroscope at thinkgeek: http://www.thinkgeek.com/product/eafc/

I love my RC helicopter which shoots missiles. Charged via USB, I got a right bargain.

Bought a little broom that cleans my keyboard, attached to the top of the monitor. :)
