Wish I'd thought of that... Wait, I DID!

Whenever I'm in an airplane, I look through the SkyMall catalogue. It's always an interesting mix of great ideas, snake oil, and raw consumerism.

An ad for image mosaics caught my eye. You can see an online version here.

Basically, they created a mosaic of Lincoln using political campaign buttons. What a great idea! I wish I'd thought of that!

Oh wait, I DID have that idea. Or, more accurately, Craig Kaplan and I did.

It's from our 2008 NPAR paper.
