Rubix’ Mod

Contains various toys, all of which can be optionally enabled or disabled. The default is that they are all disabled. More to come! (note: these would absolutely be separate mods, if my entire lifetime track record gave any indication i was capable of maintaining multiple mods)

Gay Grass

Covers the world in pride flags using the biome tint for grass, water, etc. Fully data-driven so you can add your own pride flags (or other images) and change the configurations for existing ones. Also quite optimized to ensure you can drive the settings way up without getting bad performance.

Also contains video support, allowing you to even play videos on the grass! …with limitations.

Redfile

A redstone profiler. Measures the lag caused by a redstone contraption, but isolates the measurement to just that one contraption, allowing for as good as sub-microsecond precision in some cases. More than that, it is very informative, as it can break down the lag by block using a heatmap, and by the type of processing (neighbor update, tile tick, etc). It also includes measures against common pitfalls, for example it automatically accounts for the potential error in all of its measurements. Simple for simple tasks, and complex for complex ones.

Suppression Blocks

Blocks that disable various mechanics on each of their surrounding blocks. Great for learning how the game works through experimentation, or for teaching how it works.
