Seems a great addition for the younger age range :-)

I did notice that even on a high specced laptop (1.5Ghz, 2Gb ram,  
broadband connection) the background image was very slow to display  
(until it had been cached locally).

One suggestion, 1600x1200 seems a bit large (even as a max size). For  
the XO, 800x600 (max!) would seem to be a fair max image size to save  
nand space and keep image quality. The XO screen is capable of  
1200x900 in black/white, and 800x600 seems a reasonable number for  
it's colour resolution abilities:
