Last night PT and I got to check out the Math Midway (soon to become the Math Museum), including the square trike PT already posted. Check out their website and mine and PT’s photos on Flickr. That other lovely lass in the pictures is Alicia Gibb from Bug Labs.

The Math Midway is in NYC until October 14th, at the Urban Academy, after which it will travel to the Da Vinci Science Center in Allentown, PA. This group of exhibits wants to turn into a full-scale museum, so if you’re interested in getting involved, now’s a good time!

    I would love this in my room for guests to walk through. What is it called! How did they make it! Is it a laser on some parabolic mirror?

      It was a big round frame with a bunch of lasers along the circumference, all pointing in towards the middle. There is maybe a mirrored surface along the inside of the ring, but I can’t remember.
