A hobbyist made a 2x2 angled LEGO brick with a computer and an OLED display embedded into it: [this video] This is a mind blowing level of miniaturization, especially considering that this was assembled by someone at home with commercially available off-the-shelf parts! The fact that he used a cheap, readily available 3D printer to manufacture the jigs and mould parts is the icing on the cake. When I grew up, computer monitors were heavy and had big vacuum tubes in them made out of thick glass. At the scale of a LEGO brick, it was already amazing having a single LED light instead of an incandescent light bulb! A working computer!? With a display? Madness!

as you mention gaming – do you know the doom-in-lego-brick? [LINK] and brick assembly [this video] There are some video links in the (german) article [LINK] . Mind-blowing.

His stuff is fascinating. He first came to my attention when he built the working LEGO computer bricks, as shown here: [this video] This shows it being built but if you want to see it working, jump to just after 12 minutes.

An earlier iteration of the same block is imo more impressive in its creativity - [this video] - such an unexpected and yet completely natural extension of the brick set.
