Wanting to approach the simplicity of the famous LED Throwies, the name LED Kissies was already lingering in my mind, even before I came up with the concept presented here.
LED Kissies are ”kissing robots” reduced to their essential parts: an LED, a battery, a strong magnet and (optionally) some card with a picture. They are easy and fast to make and pretty low cost.
Here's a short video:

2 Blinking LEDs working on 3V. Some blinking LEDs are clearly underpowered on 3V. I used LED's from Opitec (n° 236135).
2 Lithium coin cells delivering 3V each. The thin CR2016 type is easiest to work with, but with some bending of the LED legs, other types can be used to.
2 Strong magnets (Neodymium type). I used 4 mm thick/8 mm diameter ones from Opitec (n° 208305).
A couple of square cm of card stock. Photo card stock/paper works well.
You will probably need scissors and a printer to make suiting pictures. But you could also use ID photos.

Just take care of fingers getting pinched between strong magnets. But kids can learn to take care and it won't kill them.
Also the distance between the front LED leg and the battery needs some trimming. So I wouldn't do it with a large group of very young children. A small group or 6+ should be fine.
I didn't try 3D figures yet, but I think that from this very basic version things will evolve back to more "3D versions" again.
