I am a big fan of 7-11, I survive on Diet Coke Big Gulps. Recently I tried a Monster Black Ice slurpee, I did not like it, but I liked the holo cup it came in. 7-11 often does special holo cups: Hulk, madden, Halo, Iron Man, etc...
So I played with making BAT chest panels (pics below). I would like to play around and do a Bar code BAT,or maybe cut out a letter or symbol such as an M for MARS BAT, or some flames for the inferno bat. NFL Bat to take on the Fridge or Bazooka...
I cut a chunk of the cup, heated it in water to flatten it, and put it under a TV for two days to keep it flat.
While not as good as the origninal, I think it looks better than an empty silver chest plate. I need to refine my cuts so they are a bit cleaner, but again, this was just proof of concept
pics are worth 1000 words:
