I am a huge fan of most MOC's but i have a particular soft spot for Tri Logos as a MOC collecting area its really exspansive and there lots of variants out there. I think they look awesome on display theres the Cool Logo, alternative cardback images and clear bubbles to boot!
What more can a MOC collector want!
Heres a great link from theswca for anyone who has seen it
The 8D8 packed with the cardboard between the figures legs looks pretty mad!
