guessing the flash needs to be bright enough for the eyes to need to readjust (guessing thats when the "dissapearing" happens?)


xenon flash tube? (eg like in a strobe light or camera flash) .. thats pretty bright though .. could be a bit unpleasent to the viewer


back in the 80s I put together a little strobe light (for use at a small party) with one of those tubes - from memory only a few (not many) $ at a local electronics store


these days there seem to be some pretty bright leds about ,.,, not sure if bright enough for that but probably worth a look if any are (probably even easier to use - no high voltage components or delay for charging a capacitor as is the case with xenon tubes)
