Thursday Cool Links: Switch Sign, Blinky Box and Tiny Arcade

Wednesday naturally turns into Thursday, so the links seamlessly migrated from Wednesday to Thursday too… They are not allowed to Friday though, otherwise they will turn into pumpkins. Er, I mean Friday-not-so-cool links. Which will be just unacceptable!

Hello World. A sign built from 5,000 rocker switches.
An enormous grid made of 5,000 orange rocker switches by Valentin Ruhry. They illuminate when on to create whatever message/image.
3D printing free standing liquid metal microstructures
3D printing liquid metals. We’ve played with solder & soldering irons for a long time, and this looks…familiar!
We’ve found the awesome singularity
A tardis and a transformer rolled into one, 3D printed. Created by [Nonnef], see it on Instructables.
Programmable Toys: Blinky Box!
A custom toy for a two-year-old programmed to change light patterns based on buttons pressed. Reprogrammable for more complexity!
The tiniest arcade cabinets you’ve ever seen
Half a dozen of arcade cabinets shrunk x20, with real LCD screens and glowing coin acceptor slots, qualify for the cutest thing in the category of nostalgic (by [Dave]).

The illegal migration of links is strictly prohibited! By me. I’m gonna go hammer them down with nails so they are not tempted to run away, and keep them like that until next Wednesday when I hope I can catch them on time before they start packing up to leave.
