I have completed Simon - the game. If you have a couple of minutes, please have a look and get back to me with the good (hopefully) and the bad. I used SVG to ensure that the circles remain circular when you resize the page.

Thanks for the input. I remember reading (Wikipedia?) somewhere that this is the way the original game worked. Annoying? Yes, for sure. When I have time I will go and put logic in to check the tiles as they are entered, and respond if an error is encountered. Again, thanks for taking a look.
