London Olympic Stadium

I recently had the opportunity to take a tour of the 2012 London Olympics construction site, and got some great sketches and photographs of the Olympic Stadium.
It's been given a fair amount of negative press over the years, but now that it's nearing completion, and having the chance to see it up close, I think it is a very elegant example of sustainable architecture.

Above is an illustration that I have composed of the stadium, focusing on the different interweaving angles that build up the structure. The Olympic rings float above it in the sky, signaling the stadiums impending completion.
