Online Paper Airplane Museum...too much joy

Absolutely one of the best sites I've discovered in a long time (admittedly, I have two young boys). Most importantly, the have 800 different instructions for making various paper airplanes (all free). They have an archive of reviews, newsletters and you can sign up for a newsletter that promises a new airplane design each week.

Hours and hours of fun...until someone looses an eye. Fold like mad and be careful. Enjoy.
