As someone who grew up in a city where there were always enough potholes on every road to make what should be a smooth ride undeniably bumpy, I can't help but think this is a brilliant way to make potholes a little less annoying.
Jim Bachor uses his mosaic skills to cover up potholes that are otherwise dangerous, unsightly holes in the road.
In the past, he did the same thing with flower mosaics in Chicago to draw attention to these problem holes. This is the best way to draw attention to a problem when its not being addressed by the appropriate parties, I think!!!
Or, I guess you could be like that guy Wanksy who was covering potholes with something totally NSFW. You've been warned.
