Played with LED strip and noticed some diodes glow when we touch them with fingers. The strip is not connected to anything. On one hand, I understand that the electric energy comes from somewhere around. On the other hand, I don't understand what exactly is happening there. Can we leverage this effect somehow? :)

@caujka The energy is coming from the case of the computer where some of the power is being transmitted through capacitive coupling or similar.. you are acting as a path to ground and thus allowing enough energy to flow for the glow.
I am fairly confident this wouldnt work if you werent touching the led or yourself to the computer.
