Kristoffer Zetterstrand

Kristoffer was born in 1973 in Stockholm and is a Swedish artist.

Kristoffer creates classical paintings, but they are often influenced by pixelated computer graphics and 3D worlds.

The painting blocks in Minecraft were all drawn by him. The file in which the paintings are stored is named kz.png, the "kz" being his initials.

Kristoffer is Ez's brother, and so, is Notch's brother-in-law.
