Observe this impressively accurate reproduction of the ASPHD(aka portal gun) from Valve software’s acclaimed first-person-puzzler -

My boyfriend made this ASHPD for me for my upcoming Aperture Science Test Subject costume. It lights up both blue and orange along the tube and in the barrel, and the prongs light up red as long as the gun is on.
