The thing that got me into computing was watching an engine simulation my dad, a mechanical engineer, wrote in BASIC. He wanted to get some numbers on the mechanical advantages of various crank designs, so he only simulated the piston, crank, and crankshaft. And it chugged at about 1 fps on a TRS-80 Model II. But still, seeing that piston and crank arm move made me realize computers are capable of truly wondrous things.

And if that was the Lv 1, this is the Lv 99.
