A couple of young men in the Chicago-land area are working on a 1/2500 scale Borg Cube. I don't think that it's exactly 1/2500 as far as scale is concerned w/the Borg Cube as seen in TNG's "Q Who?", but it's of a most impressive size, regardless. It's also only about 6" "deep" and not a full Cube.
Anyhow, these young men need our help with bits-n-bobs to cover the surface of their model. If you've got anything in the way of sprue you can send them from old kits, I know they'd be most appreciative of your assistance. For reference, see the 1/2500 Borg Cube thread at The 2500 Page Forums. They're even willing to cover the cost of postage of sprue to their location.
With your donation, you can help make a Borg Cube a reality for these young men.
