Beta 1.7.3 Texture Pack Showcase
It's unusual to showcase this with default textures, but it's included here for nostalgia purposes. I couldn't be bothered watching wheat grow as well, so ignore that.
Unique Spawn Eggs
The spawn eggs were probably the most time-consuming part of the pack due to item models. It's supported for 1.20.1 to 1.8, with OptiFine required before 1.13.
Alpha v1.1.2_01
The first version of Minecraft that MCPatcher supports, but this doesn't feel right...
The Aether Beta 1.7.3
Added for the modded nostalgia people. The pack includes support for The Aether (1.2.5, 1.0 and b1.7.3) and Aether on Station API (b1.7.3).
Tall & Short Dry Grass
Dry grass has a 28% chance of replacing a dead bush. I can't remember why I picked 28% when I wrote this. It's supported for 1.20.1 to 1.8.
Redstone Repeater, Comparator & Torch
For the redstone lovers out there! Supported for 1.20.1 to 1.8.
HD Ghast
Absolute nightmare to screenshot. Supported for 1.20.1 to 1.6.1.
CTM
Modern textures for connected textures, OptiFine, MCPatcher or equivalent required.
Bush
Finally... bush. Has a 2% chance of replacing short grass. 1.20.1 to 1.8 exclusive.
3D Bed Model
Gotta get the legs on camera. 1.11 to 1.8, added in vanilla from 1.12 onwards.

I tried to get as much as I could in a screenshot, and this is the best I could do.
