I did that to my double car attached garage several years ago Peter. Wish I hadn't now. Unfortunately the garage is our main entrance/exit spot for outside (mud room is off the garage entrance to the house) and also to the rear deck and pool so it gets a lot of traffic. Need to put runners down for the winter. For my situation it turns out to be just too high maintenance. For a garage that doesn't get my kind of traffic it may be OK. It does look cool though. Here's a pic of the one side.
If I recall the vinyl tiles came from Rona or Home Depot.
