• A presentation in two parts:• 1. Pieter Sijpkes will talk about:• An overiew of ‘outdoor’ ice construction in history,
including some large scale experiments at McGill Campus• 2.Eric Barnett will talk about• Pioneering work done at McGill using laboratory-based
small scale ice rapid prototyping, a product of collaboration between the School of Architecture ( Prof. Pieter Sijpkes) and the Dept. of Mechanical engineering ( Prof. Jorge Angeles), most of the research and development executed by Eric Barnett (PhD), now a post doc at Laval University.
