I'd rather have seen Spaz in a different pose. The one with the bird on his hand already exists.

EDIT: Here's a little experiment I did with Texture Maker.

I used a clouds texture I found on Google Images, and I applied it a distortion script I wrote, one that emulates the warp horizon texture mode used by JJ2.

The script lines I used are the following:
TOP:
ox=-((x/5)-0.1)/(y-1)
oy=-(y/10)/(y-1)
BOTTOM:
ox=((x/5)-0.1)/y
oy=((y/10)-0.1)/y

To make it actually work like a JJ2 texture, you would rather use (x/2)-0.25 than (x/5)-0.1
