A funny thing to use the Jarags for is to have them as a screen where each bulb works as a pixel in a big picture.
That can be done with a videoserver.

A funny thing to calculate is the size of full HD 1920*1080 pixels.
That means that you need 82944 Jarags.
That’s an effect of 155 MW
To supply them with power you need 564 times 400A powerlock.
It´s actually 1/7 of the power from one nuclearreactor.
And the “screen” should be 230*130m
That’s the size for 6 football fields.
Maybe that screen can bee seen from the Moon.
Or maybe use it as a TV set for ISS.

Check them out, they are simple but can be used for a lots of good effects.
