well, we here at weta have finally been cleared to show some of the design we did for avatar, a quaint little film you may remember, it came out last year and had blue hippy cat people in it. so over the next little while i'll be uploading some of my concept designs here.
this one was my first and really the only design we did for the cannon the amp suit carries. my thinking was that it's based around a 20mm aircraft weapon, that's been modified for use by the robotic humanoid AMP suit. hence the somewhat fabricated appearance and the big welded grab bars. this design was modified, according to jim's needs, to the final thing seen in the film.
