Good news - Cesium was accepted to Google Summer of Code. Here’s our page:
http://www.google-melange.com/gsoc/org/google/gsoc2013/cesium
If you are a mentor, there is a link on that page to formally signup as a mentor. Have at it.
Please do what you can to spread the word, e.g., twitter, etc. To help, I’ll write a post for the Cesium blog soon.
Thanks,
Patrick
