A really neat concept/idea as well as execution. I'll be sure to mention it on my C64 related show tonight!
It would probably behoove me to add - the show content is primarily playing c-64 remixes and me talking about various c64 related (and non-c64 related stuff). Recently I've finally gotten the visual output up and running so I broadcast a c-64 like output via YouTube.

Organic google search perhaps?
