3T3 is a very simple and clean texture pack which changes the look of almost every block, item and mob. The one thing which surely looks unique (in a good way) is the sun. It has a much more clean design than the default one. Everything have very straight lines and there the colors are really well put together.
We definitely recommend this pack for anyone who want a more simplistic style to your graphics.
The simplistic addon is an optional texture pack which can be added to the main textures. They look much more simplistic than the normal 3t3 textures.
Make sure the SimplePlus pack is selected in the following order for it to be applied correctly in-game.
