I'm not sure why, but I'm unable to post some code here, which I did on my Foundation Degree in Enterprise Computing (MMU), as Blogger thinks my conditions are HTML tags... so anyway, I did this bit of Java to learn about using back buffers and for no other reason, and the link to the code is here:

Take a look, and post your comments here. Note: some of the code might be depreciated now, but I'm sure you're clever enough to work it out.
