My room during my senior year at Purdue overlooked the rec fields. After a snowstorm I looked outside at the huge field of white and had the idea to go write a message. A quick AIM chat (hey, it was 2002) with my friends didn’t reveal any great ideas for what to write. The best we could come up with was SPACE FOR RENT. We of course came up with a lot of great ideas the next day. It went over pretty well. I heard a number of positive conversations about it on campus.
There’s an artist named Simon Beck who really takes trampled snow to the extreme. He creates works of art on a huge scale in the snow. Check out this post for photos of his work.
