It's a series of TUBES (and PNGs).

As IEBlog notes, Microsoft's "Zentek" demo is finally online for all to see. I'm hoping that they optimize the better PNG support to match the speeds of Opera 9. Also gamma.

I'm hoping the Series of Tubes dance remix wins moheevi's remix contestThe Tubes mix got an honorable mention and a spot on the YTMND Soundtrack. Sounds good to me.
