Hey, I'm curious if I could use this in a commercial project I'm working on, was looking for a simple arrow rain animation and found it.
I originally made this for this contest which was supposed to make all the animations available for everyone to use. I wouldn't have submitted it if I wasn't okay with people using it, but I don't know if the people organizing the contest actually made like a download pack of everything with a license and all that.
Feel free to use it. Maybe drop a single line in your credits or something (I don't have a license for it, as I expected the contest to take care of that) but, yeah go ahead. If you'd like me to actually put it into creative commons or something (just so you have something to point to if people ever got pissy for some reason), I can do that I'm sure. =)
