So, i'm a worldbuilder by soul and a computer guy by education, but I had a random thought.

Light matter and Dark matter, if one were to take the residual energy that they naturally shed (assuming they do, going off of watercolor matter here) and use it as ones and zeroes in computing. Would it technically be possible to make a matter powered computer? Obviously wouldnt do anything to harm the matters in question. It would just run off and I assume the matters could be let free to roam and play when the machine isnt needed. Or something like the rotom phone from pokemon. I was thinking like a matrix of matters around a central core and the orbit fuels the calculation process, or if the matters are inherently hostile to each other in separated vats or somesuch.

Thoughts?
