Heres a little concept from mcornetto called "The Dark". Write up a short script based upon the darkest regions of your mind and if selected it will become part of a moviestorm feature. The Deadline for the script is this friday so it's short notice but could be a pretty cool exercise. Full details can be seen at SimplyScripts.
Be sure to check out the (pretty well made) concept reel here.
Added link bonus today of a somewhat underseen multipart (as yet unfinished) MovieStorm project from Kibishipaul...
