Is there any honest to god Portal guns out there?

I mean the thing from Portal, not substitutes, if there is one, I’d like to see it, if you’d be so kind. If they don’t work, why?

As far as things go right now, Blackops’ Portal Gun comes as close as you can to the real thing.

:sigh: If only Mahalis’s portal gun still worked…

This is meant to be good though, bit buggy but at least works: http://www.garrysmod.org/downloads/?a=view&id=110088
