I'm planning to do a few now that we start to emerge. Sign up for the mailing list or follow me on twitter, I'll announce the blog posts there.

Basically we have a client side rendering engine combined with a cluster based solid modeling kernel. To get everything interactive we have pretty strict deadlines both for the server processing and for transferring the data to the client. I used to work at Google as systems programmer and even compared to that infrastructure this is pretty interesting and hard stuff.

Edit: I'm @KaiBackman on twitter.
