Remarkable! I saw this thing on brickshelf a couple of days ago and wanted to
post about it, but I figured I'd wait until you publicly announced it. The
pictures of all the structural reinforcing that went into building this is
quite impressive. The back end, with the curves and ramps to the second floor,
look like sculpture. Well done!
I think that the reason the deck bowed like that is the nature of the way these
parts are made. In order for normal plastic parts to be injectable, they need
to have a draft, or angle, on the vertical walls, otherwise the part wouldn't
slide out (think of the way an ice cube tray is designed for an extreme
example) I suspect that lego parts have a very very slight draft on them,
barely enough to allow them to be released, but not enough to really be visible
to the naked eye. It only shows up with a long chain of parts like this, where
the slightly non-vertical surfaces conspire to curl long plate sheets.

These show some of the details and the construction process. (URL) is seven feet long, two feet wide and (...) (22 years ago, 26-Mar-03, to lugnet.announce.moc) !!
