I love the jQuery UI icons but they are just too small for my particular needs. I develop educational lessons for kids and they need big icons. 

I have hacked up my own solution but it hard to maintain. I took the jquery ui sprites and increased each by a factor of 3. I then went multiplied all the css dimension information by the same factor. I also have to tweak my own css to position the bigger icons properly.

Is there an easier way to do this?
