Oh, i have new ideas!
Actually i don't know what it should to be element or wall... Anyways:
1) Lamp - release photons when charged
2) Capacitor - accumulates charge and releases it under some conditions. (But for this idea will be better if current in TPT will have amperage parameter)

What would you say to this?

Just an idea, but maybe a element that is semi liquid, semi solid.

Unlike water which will spread out very quickly or stone that will barely spread out at all, this element would very slowly spread out and aim to remain in contact with other particles of itself.

I'd like LCRY to go completely white or black upon spark. It makes it harder for quick, large clocks if the LCRY takes forever to be completely lit up.

Another little idea:
Solar panels - generate electricity when exposed to photons
(although not sure that it is very necessary thing)
