Martha Street Studio, a community-based printmaking studio run by the Printmakers Association of Manitoba, recently had their second "Under Pressure" Steamroller Print Festival. (via Whipup, photos by perfectbound)

For the past two years Martha Street Studio has hosted 'Under Pressure', Winnipeg's only Steamroller Print Festival. High school students, community groups, and artists from across Winnipeg create large linoleum carvings leading up to the festival. On the day of the festival the carvings are inked and printed with the aid of a real steamroller.

I found this slide show of the Imagine RIT Innovation and Creativity Festival's own steamrolling art. They also used skateboards and breakdancing! (via Water Based Inks)

It turns out steamroller printing is pretty popular - who knew! Here are videos of the steamrolling process and a print pull.
