Writing your own ray tracer is a blast, but to add a festive twist, how about rendering something holiday-appropriate with it? Here's an ornament I rendered four years ago, using a ray-tracer I wrote myself. (Pseudocode for the scene itself is available here: https://forum.raytracerchallenge.com/thread/16/merry-christmas-scene-description). What have you rendered lately?

Finished these two teams for my son and I to use in #gaslands; I’ve got a box full of more HotWheels cars just waiting for similar treatment, one of these days!

A 2D maze is just a sequence of 1D mazes with "warp portals" linking them. What if you render it like that? Take the 2D maze, shuffle the rows, and then use colors to indicate interconnections. Each little dot lets you warp to the same column in the indicated row. Here's an example -- can you get to the exit?

A heavy weave applied to a masked grid:

Ah, and there's the look I was trying for.

Sometimes, the mistakes are as fascinating as the successes... (Trying to make a polar grid with uneven radial widths. This was my first try.)

Playing with parametrically generating geometric masks for mazes. It's a fun brain-game!

I really do love my name, but sometimes I wonder what it would be like to be called Tim, or Bob, or almost anything else…
