Many, many thanks to ZeHa for creating and hosting the competition, from a great idea, a perfect invitation (which could have been an entry all by itself), to organisation, hosting of the whole event, and, of course, participating with a wonderful entry! And many, many thanks to Dan for co-hosting it, delivering the first two entries (which both were setting quite some standards!) and creating the compilation disc! And many, many thanks to the MEGA 65 team and community for providing us with platform and support, without which we couldn't be creative.
I will soon provide a commented version of my source code on filehost. After that ... I have plans for several future projects, but did not yet decide. :-)
