A number of people have requested instructions to build their own version of a Lego Cray-1 Supercomputer - As a result I've published them here (as a pdf) - The original Cray-1 was modular in it's design and configuration and the instructions are for one "module" of the Cray-1 and I think 8 of the "modules" should give you a complete Cray "Ring"
The full instructions can be downloaded here (pdf 3.5Mb)
A version of the Lego Cray-1 model was installed earlier this year at The National Museum Of Computing which is located at the iconic Bletchley Park site near Milton Keynes here in the UK. Bletchley Park is famous for the code breaking endeavours of Alan Turing and his team during World War II. As well as having it's own Cray-1 Supercomputer on site, the The National Museum Of Computing has many fascinating computing exhibits and is well worth a visit.
