I had an idea yesterday morning…
…and I won’t type out the whole of it, but it included a short white staircase with a strip of plexiglass on each step that reveals LED light underneath the step. The light is connected to a sensor that causes the step to light up when you step on it.
Here’s something similar which of course encourages me to keep dreaming because obviously…it can be done.
I’m so on to something here.
