Its not just the Conveyor Belt. Its realy a brick pack with velocity zones. (conveyor animation not included)
i once made a working FLYING aircraft carrier with this idea, but i don't think it's gallery worthy because it's missing a few things and not very detailed.
aircraft cariers dont fly
The carrier would have to be realistically scaled to a blockhead. You wouldn't be able to see the other side. Good idea though. It could be used for a TDM.
