Made for Disty's architecture contest. A quick little entry and nothing fancy, but I wanted to make an entry of some kind and those treads jumped out at me as perfect for a bridge. Purple tiles because I have little System and purple is a great color anyway.
There's a fair bit of System with the studs, cheese, and tiles, but with all the pins inside holding it together I think the System's less than a quarter of the parts.
And a Merry Christmas everyone!
