British national museum of computing started conversation work of the Colossus hall. Colossus is one of the first programmable computers designed to solve cryptographic problems in 1943 by Tommy Flowers. Colossus second version was used by UK intelligence at the end of WWII to decrypt german messages encoded with Lorenz SZ40/42. Colossus use vacuum tubes for the calculations. British museum of computing has a special hall dedicated to that machine that currently is closed due to undergoing conservation. The museum started online fundraising campaign for Colossus hall. The fundraising site follows interesting concept of selling pixels. The idea is that the contributors buy certain amount of pixels from the Colossus photo published on the site. The pixels are replaced with an image selected by the contributor and linked to the contributor’s site. This fundraising approach was first implemented by Alex Tew with his million dollar homepage.
