Hello,
I've been working on a parallel particle programming system called Kedama. The last version wasn't quite good enough to announce, but I feel this version is a bit better.
Kedama is deeply inspired by StarLogo and StarSqueak. In Kedama, you can control thousands of objects with eToy-like tile scripts.
Please take a look at:

and give it a try.
Thank you!
