Ohh I actually saw something similar to this. An artist had some project at his school that involved this type of art, of pixel-like art.
And he came out with this brilliant idea of collecting all keyboard keys, whatever the colors, he would take the old keyboards and collect the letters from them.
He painted those letters and he created lets say Van Goth style of art using only keyboard keys.
I'm sure everyone saw at least once this video that showed off his way of creating art.
Pretty neat. Im not a Lego collector and dont have wall space for things like this so I wont be getting it but it is a good idea.
Outside of an occasional free SDCC giveaway or something along those lines the only Legos I have are from my childhood (The space station set). These have been sitting in my closet but just the other week I decided I should pull them out and find space for them in my new toy rooms configuration. So about a week ago I went through them as well as some other builder sets I had as a kid (Construx, and a Non brand international medievalcastle brick set)and constructed them for the first time in decades. It was fun, and now I have a lego/brickshelf included in one of my toy rooms
