This is probably one of the best projects I've made so far. Pi, the number not the food pie. check the code to see how complex this project really is. Few bugs but maybe that's just because I'm using an old MacBook Air.
A visual description of the famous Pi. you see that the end of the Pi line will never meet the start, it will always be millimetres of millimetres away if that makes sense so that is why pi goes on forever and ever.
