Ha, hadn't thought of it that way, but I can see what you mean. I added it to play around with Canvas, while tying in with the half-tone dot motif in the header.
It could definitely stand to be a bit more subtle, though.
I like the trails. I didn't even notice them until they were pointed out as I don't move my mouse around much.
I also usually put an exit() after redirects, just in case.
+1 for the trails. Have fun. Do what makes you happy on your own site!
I liked fun things like this. Within reason. And this is within reason.
