I really liked your demo and I'd like to see what your WebGL startup will do. Is
http://figma.com/ the right place to sign up to be notified when it launches?
Edit: You might want to add some more visual feedback (e.g., blanking the email input field or hiding it) when you enter your email successfully on the front page of figma.com. I had to launch Firebug to make sure it accepted my email with a 200 OK because that check mark icon appearing briefly while the email field's contents stayed the same seemed suspiciously like a silent request failure.
