RULAV is pronounced "AWESOME"

Rarely does building a treehouse require welding, grinding, painting, riveting, bending, crimping, plumbing, brazing, laser cutting, sound design, printed circuit board fabrication, thousands of lines of C code, distributed network protocols, sewing and embroidery. Ours did.
The Ravenna Ultra Low Altitude Vehicle is a hexagonal capsule, 7.5 feet (2.3 meters) high, atop a tripod 7.5 feet (2.3 meters) high, for an overall height of about 15 feet (4.6 meters). It is about 6.5 feet (2 meters) across at its widest point.
The frame is welded mild steel with riveted aluminum siding. It contains nearly 800 LEDs forming dozens of numeric displays spread across 14 control panels, each with an acrylic face laser-cut and etched with labels such as "Lunar Distance" and "Hydraulic Pressure". The pilot controls the rocket using a joystick and panels full of working switches, knobs and buttons. Underneath the capsule are three "thrusters" that shoot plumes of water and compressed air under the control of the pilot's joystick, simulating real positioning thrusters. Takeoff and docking sequences are augmented by a paint-shaker that simulates the vibration of a rocket engine. Sound effects complete the illusion, with a powered subwoofer that gives the rocket a satisfying rumble.
It's basically the treehouse that you dreamed of your dad building when you were 6 years old and obsessed with NASA, except that these guys actually went out and did it (with some help from their friends, and a lot of supplies from Boeing Surplus).
In addition to the tour / intro video, the site features design details, build history, prototyping info, schematics, and even a downloadable version of the treehouse's RULOS operating system.

Oops. Small correction - it looks like the blog was actually mostly written (and the RULAV designed) by Elliot's Mom, which honestly makes it even more awesome. :)

It's a good thing I probably will never have children, because I am fairly certain they would never forgive me for not being equally awesome.

Looks like planning it and building it was way more fun than the actual result. The "blast-off" would get old pretty quickly, once you've shown all your friends, and there's not a whole lot of room to, well, do anything in it. The process of creating it, on the other hand, must have been a blast.

Tie between Angry Birds cake Dad and this Dad, but only because Rocket Ship Dad didn't give the kid a moon rover to tool around in once he lands.
Seriously, though, this is awesome. As a Mom of boys myself, I'd bet good money this kid jumps off the topof that ship once he's a little older.

This is completely freaking awesome. That said, I think a great addition would be a small (detachable/portable) DVD player running video loops of outer space/planets/the universe.

1. As stated, this is NOT a tree house.
2. I hope that the neighbors live a LONG way away, because if that was in my neighbor's yard I would be pulling the plug on the noisy contraption pretty quickly.
3. Seattle, where it rains, and that much exposed electronics in a metal frame with kids in it? Thank god it runs on 12 volts!
All that said, it's pretty neat.

This is cool, but as a treehouse it fails the very simple criterion of not being in a tree.

Plenty of room to read, which is what I did in my treehouse. (OK, it wasn't really a treehouse, it was just a cherry tree with a spot up in the branches that formed a fairly comfy seat. But still.)

This is possibly the ultimate geek family:
Well, that logo's so classy, it needs to go on a patch! I could have had it done for maybe $80 at some web vendor. But why do that when we can spend $200 on craigslist for an old embroidery machine, and learn to do it ourselves? The embroidery software I used to do the patch was pretty awful. In the spirit of do-do-it-yourself-yourself, I wrote my own embroidery software for inkscape.
Of course you did!

Neat, but yeah, I'm with halogen. This seems to be more about the adults' building (and bragging) experience than the kids' playing experience.
It's a super-sweet rocket ship, but that's all it is. Once you've played that game a few dozen times, what next?
It's like an expensive electronic toy that does exactly one or two things vs. a bag of Legos, a refrigerator box, or...a little wooden room in a tree.

When I was a kid our(my brothers and I) first spaceship was a cardboard box. We then graduated to the combine cab. Then my parents got a minvan. Things got really complicated when we decided it would be a good idea to back the minivan as close as we could to the combine. If I remember correctly the idea behind that was that we could use The combine as an escape pod for when our minivan was blown up by enemy fire.

It's a good thing the kid's wearing a helmet when he climbs the ladder and opens the door, because it's made of metal and the hinged side is angled well forward. Which means it swings downward, under its own weight, when unlatched.
They need to put a damper on that hatch because somebody's not gonna be expecting it, get clocked in the head and fall backwards off the ladder. The corner looks a little on the pointy side too.

I noticed that, too.
Ideally, the door would also be split in two (one half hinges right, other hinges left), so you don't have that dangerous swing-out of such a wide and heavy door. Or maybe some sort of garage-door type dealy.

It strongly resembles a deer feeder. In hotter climates your children would cook in that solar oven. It's pretty cool and they worked hard on it, but it seems like the novelty would wear off quickly.

You are not getting the awesomeness here. It is 10% the end product, 90% the process. When my kid is interested in NASA, I buy him a book and maybe some space ice cream. I don't embark on a months-long family engineering project to build him a frickin' lunar lander.
