I have been working on 15 minutes play blocks which are very random and I have been thinking about putting stripping around them. On the 15 minute play blog, there a lots of samples that people have posted so you might want to look there for ideas. I have become possessed by scrappy and wonky blocks. My blocks are posted on a blog that I started so my friends here could see what I was working on while I was out of town for a month.
