In Ken MacLeod's novel Newton's Wake, a "lightning chaser" is someone with (an almost pathological) fascination with TransHuman technology. In MacLeod's universe such individuals are viewed with distrust, due to the particularly cataclysmic nature of the Singularity in humanity's past.

Lightning Chasers may not be interested in provoking a Singularity themselves, though they can't seem to resist exploring and tinkering with TransHuman technology whenever they find it. This often leads to disasterous results, ranging from the lightning chaser becoming "infected" by the technology being studied up to provoking a new, local Singularity.
