Green Product Idea: Thumbs up or Down or Sideways?

michaelbrashier.blogspot.com — Diggers, For my entrepreneur class I'm doing a little market research on a product idea I had. I'm developing a product that turns ordinary plastic bags into Lego-like building blocks. Digg it or comment if you or someone you know would buy one for less then $100. Also give me as much feedback (neg or pos) as you want. PS I reposted to new blog.
