It has transpareny in the corners. Maybe it's only a technicality, but its still within the rules I think.
I really wanted to do the dark background one, but I felt it practically broke the rule of transparency. Not much point of transparency in a pixel if I throw a background behind it. After the challenge voting is over, I might change it to the background one.
grey is barely visible on the PJ background....preview looks better!
Should've uploaded the version with the dark background imo. Cool stuff either way, the animation makes it.
I'll go for it then.
