I was browsing around and stumbled onto this image from a blogger in Japan (( http://mokei-ya.cocolog-nifty.com/ ))
They had a fun way to "break up" the somewhat squared off Unitram road plates. I really like the idea!
I think I might have to take something like this on for Shizuka. I'm going to have to look at the arrangement to see if my space would allow for something like this.
