#AdventOfCode Day 20 - Race Condition

Showing millions of cheats is tricky so this one turned out a little weird =). In part 2 it repaints the points by their total possible cheat gains. Pretty neat structure shows up.

#AdventOfCode Day 21 - Keypad Conundrum

The robots almost broke my brain this morning, this was super hard for some reason.
But at least the solution works pretty much instantly.

#AdventOfCode Day 19 - Linen Layout

Some dynamic programming if not dynamic visuals.
No idea how to show full input, there's 400 sequences there =).

#AdventOfCode Day 16 - RAM Run

I did a binary search in part 2 in my actual solution but watching how the path rebuilds after every new obstacle is pretty fun too.

#AdventOfCode Day 16 - Reindeer Maze

Looks full of holes but it is a thorough search.

#AdventOfCode Day 15 - Warehouse Woes

box is push
robot is move
star is win

#AdventOfCode Day 14 - Restroom Redoubt

Checking density anomalies for fun and profit.
I love how the vertical density chart itself sometimes looks like half a christmas tree.

#AdventOfCode Day 14

You wait a few hours, then one blink and it's gone 🎄 😄

I don't have a good day 12 animation yet because damn, getting a sane ordered contour was much harder than just counting sides.
But something finally works even for the crazier shapes like this one.
