He was within earshot, and was all, "Let's do it!". The rest as they say, is history :)
Behold, the Holtzmann proton pistols (or at least one of them, the other needs a bit more paint)...
Made completely from EVA foam and some well-placed LEDs.
This set is pretty darn amazing for a quickie round 1 version, and done in time for a fun, albeit silly, tribute cosplay I have in the works.
I'll post more on this project in the coming days, so stay tuned!
