Neat!

Nice work from the Harvard kids.

I'd bet that many of us (especially those of us who are teachers) would also really like the PhET sims.

I particularly like the projectile motion sim, because you can change it to shoot a Buick, a grand piano and a bunch of other goofball things.

Some of the other PhET labs, like the chemistry sim are amazing.

I think I just went into some sort of trance...

Practical application with art. NOT grassroots but cool none the less. http://www.hodinkee.com/blog/2011/4/5/turning-mechanical-resonance-into-an-asset-with-the-fp-journ.html

Awesome! Mrs. Javelin's Physics students will appreciate the video!

(On another note, now she'll want me to make her one...)
