Wow can't believe it's coming on two years since I made this thread. I tried making the base the Master Chief's glove cradling the chip with Cortana in the middle of it, but wasn't happy with my results. I ended up just sculpting some clay to look like a rocky base with the chip resting in it. I then primed it and weathered it till I was satisfied. One day I might rework the base, but until then I'm happy with it.
