Playing with Lego Data from Rebrickable

Ah, the good old childhood days of playing with your Lego sets. I went down this memory lane last week when I visited a bookstore and found a Lego play area. I added bricks to someone else’s tower and built a car next to it. #opensource #ftw

Fun fact: “Lego” was derived from the Danish phrase leg godt, which means “play well”.

In this analysis, let's explore the colors of the bricks and the different parts and themes of the sets.
