A Simple Counter. I have set it up to run up to and including a 5th digit. 2 digits pass per second. When I used only units, tens, hundreds etc the change over to 100/1000 was out of sync by 1 so I used count, count2 and count3 to get round this (>99, >999 etc rather than >10 etc). Can probably be done more efficiently but it works as it should and has potential for more digits to be added etc.
I used a standard scratch font for the numbers.
