After seeing this latest offering from Russian design studio Art Lebedev, we suddenly have a burning desire to start numbering things.

Designed to be used as door numbers, the "Digitus" self stick pixel door numbers offer a jagged, graphical way to denote the numerals of your portals.

Available in white, terracotta, metallic blue, metallic green, and metallic magenta, the 5.5cm tall numbers can be ordered now for 4.29 euros, or $5.77 each.
