Chris Kann, the owner of wayfar.org, sells a device called the Midines. It’s a Nintendo cartridge that plays the Nintendo Entertainment System like a musical instrument, I kid you not. You insert the Midines cartridge into your NES, plug MIDI cables into the Midines, and off you go, into a world of bloops and blips.
I paid $99 for a Midines in the year 2008, and… I have still not received it. I have sent Chris Kann at least a dozen emails, and never received a single reply. In 2008, I did track him down on IRC — he mentioned that he was going through some hard times, but now it is 3 years later, and he has been completely silent.
