The light show was unveiled last night at PCS headquarters nextdoor to Clapham Junction station in south London.
The images oppose the government's economic measures and advertise the 'March for the alternative' on Saturday 26 March.
They will be projected onto buildings all over London tomorrow evening (Wednesday 23 March) after Tory chancellor George Osborne has unveiled his budget of misery and cuts.
