Thanks to Squeezyboy for pointing me towards eBay item #7350576206, a fourteen foot long MIDI keyboard. It starts at £2,000. This page seems to belong to the people who built the piano, complete with a fantastic video of it being played by some workmen. I guarantee it will make your day. It's the sort of thing that Jean Michelle Jarre would have played back in the day. In other keyboards-on-the-'bay news, #7349626808 is an original Fairlight II keyboard (like the ones seen here and here), currently just £60. I've spent a few days thinking I should buy it and
turn it into the world's most awesome MIDI controller have it gather dust in house. Similarly, how cool would it be if I wrote MT on a Fairlight Querty Keyboard?
