These guys are just straight up industrious! They built themselves a robot out of legos that throws perfect strikes on via the Wii.
"You are looking at a Wii Remote mounted on a robotically controlled swing. A second motor is used to trigger the bowling, by first Pressing the A button and left arrow, and then holding down the B button, swinging, and finally releasing the B button."
That beats the heck out of the pyramid that I built with legos. Apparently some were born to create feats of engineering, and I was born to make fun of it. They've got a plethora of pictures and a video to go with it over on their site.
