So, had the idea for a ribbon like particle system, think Leaf gave me the idea back when I was playing with the Warheads clone (must pick that back up!)
So, have written a ribbon particle system and as I wrote it thought it would make a nice Light Cycles wall emitter.
When I get around to writing up the blog post, you will get a PC and a WP7 project, the PC project uses custom shaders, the WP7 naturally uses BasicEffect.
Think I might actually do a Light Cycles clone for the WP7 :D
Hope you like it :)
