help John Graham-Cumming build Charles Babbage 's analytical engine

I just pledged $10 to help John Graham-Cumming build Charles Babbage 's analytical engine.
Babbage designed the analytical engine, a Turing complete computer in 1833, a 100 years before Alan Turing published his paper on the Turing machine. If you want to see this steam powered brass mechanical computer get built, pleas...e pledge and be a part of history!
