I am working on some education software for young kids, less then 7 years old. I joined the jde educational project and i hope that eventually this games will be part of the kde-edu distributions.
I updated the Learn to Count application, now it can be chossed at start the maximum number of items that will appear. So if the kid has problems counting a large number of items you can limit the program to display less items.
The coloring application was a little hard to code, I had to optimize the bucket fill algorithm.Now it has a good performance on my computer, i must test on older computers.
The memory game was easy to code, after adding some animations I think that it could be refactored a little to be easy to read the code.
I found a super web site that contains free artwork that can be used with no restrictions. http://openclipart.org/
