This element can be wireless, and can also either come in different colours or have its colour set by heat or another variable (wifi channel and colour should be separately controlled).
Screens are starting to become a popular creation, yet the ability to manipulate pixels in a realistic fashion does not exist. this element would allow a grid of immediately adjacent particles to be individually controlled.
tell us what you think of this idea, and if its worth exploring and petitioning to Simon or another moder to implement.
Ok here's a better idea, colour set by heat. The first spark turns it on, the second off, and then another spark will turn it back on, alternating as such. It will accept a spark from WIFI without any metal in between, but will not transfer the spark. It will also only accept sparks from WIFI directly beneath it.
