Building blocks are one of those toys that just about every kid in every generation played with in one form or another – whether that's the classic wooden bricks, the satisfying Lego or the digital worlds of Minecraft. Now Antsy Labs has introduced its own spin on the toy with Pixl, a set of building blocks with tiny embedded magnets to keep them stacked in 3D models or lined up in pixelated 2D artworks.
