A few of you have messaged in about a neat item from We Love What You Build called the Periodic Table of the LEGO Colors. Featuring 70 different colors in 12 different pieces, the table also tells you the official LEGO names of the colors as well as the BrickLink names and ID. In addition, it also tells you when each particular color was used. It sells for $39.99 and its measurements are 15.7 x 11.8 x 0.6 in / 40 x 30 x 1.5 cm.
