Very impressive and fun. Real world results for the absolute beginner. With 35 years programming in C, C+,C++,VB,VBA, ASSM, Python, C#, and a host of script languages from DHTML and ASPX, to more modern PS scripts and Eclipse Java and the lightweights. I find this entertaining and stimulating. They even stopped me up by exceeding my expectations with logic problems but not giving me information on that. A "figure it out for yourself " approach. I like that and found it fun. It was not expected. Kudos.
