I did a little Warhammer 40,000 project recently in Tau. One of the crisis suits is featured here:
One interesting thing about this guy is that his weapons and equipment are all magnetized. My client provided the magnets, and I assembled this suit and his comrades with fully magnetized weaponry. It takes a good deal more time and effort in assembly, but in the end you can alter your wargear every game you play, rather than having to commit to an army list when you assemble your minis.
I found this tutorial after I finished this batch, but it has more details on how to magnetize Games Workshop plastic miniatures with Rare Earth Magnets.
