Just in case anyone's interested in this sorta stuff, there's a Kickstarter some people I know have set up for a toyline they're working on:
http://www.kickstarter.com/projects/1822390380/bmog-bio-mechanical-ordnance-gestalts-ursenal-vs-m The concept is to make a bunch of weapons that work as accessories for other toylines, like, say, Transformers (they use 5mm posts, which a lot of toylines use). The weapons can also be assembled into animals, so the two toys they're working on putting out are a manta ray that turns into an axe and gun, and a bear made up almost entirely of guns.
The Kickstarter's only got three days to go, but I'm hoping it'll reach its target, cause it looks fun.
