Neighboring pixels feature

It would be useful to add a concept of “neighboring” pixels when you’ve established a logical re-mapping of the physical pixels. For example, if you have a typical RGB gamer keyboard, there’s a bunch of lighting modes. One is often a radiating color explosion that starts with a keypress. If you press **H** on the keyboard it’ll change color and then a radiating color wave will move next to **T Y U G J B N M** and so on.
