Many summers ago, mostly in response to the great creations we had seen online, Greg Keith and I all set out to build as large castles as our supplies could afford.
In the meantime we had a bit of a cold war buildup of knights troops and war machines and thus held a few gigantic scale lego battles - pongia 1 and 2.
Since then Keith and I have begun to explore the world of Lego Digital Designer. We spurred creation by starting with a few competing projects (we'd do something like each build a bridge on a three quarter plate base maximum). After that we have gone further to create some really fun random projects.
It would recently seem we've begun creating a matching collection of space MOCs, Keith with a neat blue and grey theme and my own white yellow and grey for the Duggonian Space Navy.
