[Charlyn] makes a laser cut RGB LED backlit birthday card.
[WolfCatWorkshop] creates a weight powered automata.
The speed is limited by the air friction of the spinning 'fly-fan' with the assembly a combination of
laser cut elements, chains and weights.
[IoT Hub] offers a very cute "safe social distance habit trainer" on their Tindie store.
[Geeek Club] has a Kickstarter for a cyberpunk PCB construction set
that uses 2d PCB panels soldered together to form artistic cyberpunk themed models.
The models themselves aren't moveable but the circuit boards look to have some functional LEDs.
[Aaron Patterson] creates a USB controlled terminal bell.
[samsonmarch] creates a pair of custom smart glasses to help with GPS navigation.

[Duke Doks] creates a 3D printed light marquee.
The fonts are extruded and the letters re-positioned to have overlap.
Each of the digits is then glued to the other, with access for the LED strip.
The LED strip is glued to the side and a 3D printed inset diffusor is positioned on
top.
Each digit has a small platform to make sure the inset diffusor is positioned correctly.
[_caseyhunt_] creates an Arduino powered "beating heart" from a Smooth-On silicon mold of a heart and a small 9g servo motor:
[Norman Wink] uses infinity mirrors, RGB LEDs and 3D printing to create a Halloween mask.
