Earlier this year, I did 21 different implementations of a hex dump program in C (starting here: http://boston.conman.org/2012/01/09.1 http://boston.conman.org/2012/01/09.1). I also included implementations in a few other languages just for comparison. Why? It was a neat break from the programming I do for work.
