4J Studios has debuted a technology called Rixels which replaces normal texture maps. Instead of individual pixels, each contain one of 23 vector shapes. A standard 512×512 texture in 4J’s Minecraft-like game Reforj required 4MB of memory. But with Rixels, the same sized grid can be made from 20×20 squares, using only 72KB of memory – a reduction of over 98%.

It works best for stylized rendering that must have massive scale.
