I'm glad to see you got some quality cel hunting in ^_~  
Others may not think that this was a groovey cel bonus, 
but with one of my Kite cels the background featured a 
nifty pasted picture.  The genga identified it as being 
made on a mac, I always knew Yasuomi Umetsu was 
an incredible artist, but this just proves he is downright 
cool too.
