This is sort of off-topic, but I just remembered another one -- Clarke's "2001."
Remember? "Open the pod bay doors, HAL!" "I'm sorry, Dave, I can't do that."

Unknown? Nah, it's Major Moonbeam, having a bit of fun with the hapless newbie.

Nor do I. But I think that the idea of every space vessel being able to dock
with every other type of space vessel is probably impossible to achieve. Most
people's designs, I have noted, are really small fighter spacecraft. The only
access is through the cockpit window.
No big deal. Many things still will work together.

I did some building last night -- and it looks like I might go for a double-
doored airlock after all. This ship is turning out larger than I expected.
Maybe I should build something smaller, for the express purpose of featuring the
smaller door design I was working on...

Well, I'm newly emerged from my Dark Ages. The model I'm working on at the
moment is my first model of significance in twenty years. When I'm done, I will
photograph it, at the very least. I'm handy with a camera and a scanner, I pay
attention to lighting, plus I have a nice macro lens set.
I'm aware of LDraw, however I haven't downloaded it yet. Nearly all of the
computers here on the Stanford campus are Macs, so I can't run LDraw here. My
home computer, a Windows machine, is not wired up -- not that it couldn't be,
but I'm totally spoiled by the high-speed, free campus connections. I've
recently graduated, and my salary isn't quite what I'd like yet. Until I have
money to burn (in other words, after I've satisfied my need to buy Lego!), it's
hard for me to justify paying cash for net access that in all probability will
be twenty times slower than what I have here. When I finally bite, I'll jump
straight to a DSL or cable modem connection.
The last time I tried to pass a binary from the Net, to a PC disk in a campus
Mac, to my home PC, it arrived corrupted. I haven't debugged this process yet.
How does LDraw perform with a model that has LOTS of non-orthogonal angles?
