Made this quite some time ago. Never got around to actually making it my own custom mousepad though.  
Perhaps somepony else can use it for their own custom mousepad - Or perhaps as some wallpaper or something ;)
 
(This is the fixed and repaired version, with the corners fine and the edges cleaned up. I could’ve just re-exported from the original vector, but I’m lazy and fixing the filter I used for the clouds in Inkscape would’ve been a pain.. _)
