This is such a good idea! It's just political signs and zip ties. Don't think I won't be doing this for my self very very soon. Naturally, I'll paint mine so they don't look like ass.
I don't know if this image will show up, but I had to try. It's also from the londonfgss forum. Note the DIY steel Aerospoke and the cutout in the seatpost tube for the wheel.
