There is probably something similar floating around, but I just got finished with this so I thought I'd share. Enjoy!

It has what I like to call 'soft' corners, meaning the inside of the corner is made of tires with a chalk line for better visibility and 'curb' effect. It works pretty well, and great for those who like to hug the inside and get ticked off when they snag a slightly askew barrier.

must make some interesting races + crashes hehe

(btw.. how do you make those "layout" screenshots?)
