concrete

Andrew Lewicki created these concrete LEGO bricks, designed to stack just like the real thing! It's hard to tell in this picture, but they're actually 15 inches long each. So, time to build a home out of these, right?

Instead of actually filling the potholes, just throw a bag of powdered concrete in there! Genius!

"I've got the most brilliant idea! Instead of people driving on wheels, why don't we just make the roads themselves out of tires! Brilliant!"

For a similar reason, Autocowrecks is a nearly indestructible site!

And by "tools of the trade," I mean these guys' supervisors.
