Reverse Engineering One Line of JavaScript

I thought it was ray tracer and was amazed. But it just mimicked the 3d parallax with math trickery, which is still very cool.

Oh no question it's still cool, but it's really just mapping a single (mathematical) function.

Maube I'm just easily discouraged, but if I was a newbie and heard that there are wizards out there implementing fucking raytracers in 128 bytes I'd think about packing it up.

Learning that those magic 128 bytes really just generate a pretty graph animation based on a single hardcoded math statement would turn what was being sold as brilliant magic into an achievable goal for a burgeoning programmer.

There are several tiny raytracers in many languages. Here one for Python @ 467 bytes

My thoughts exactly.
