RE: Kaguya (Selene) Images of Earth-Rise Over the Moon | SpaceRef - Space News as it Happens

The Japan Aerospace Exploration Agency (JAXA) and NHK (Japan Broadcasting Corporation) have successfully performed the world's first high-definition image taking of an Earth-rise* by the lunar explorer "KAGUYA" (SELENE,) which was injected into a lunar orbit at an altitude of about 100 km on October 18, 2007 (Japan Standard Time. Following times and dates are all JST.)
Have they released any true HD video or pictures yet? They list the camera's capabilities as 2.2 megapixel yet all I have been able to locate aren't even 0.5 megapixel.
Still cool. I was hoping they would have enough resolution to take pictures/video of the Apollo sites but no luck this round.

One of my favorite games is Myst...I am really interested in games where I am solving puzzles/figuring things out, etc. However, lately, I have found it quite challenging to find similar games as Myst...and at the moment, I have no game that I am working on, which is driving me crazy. Thus, I am wondering if anyone around Memestreams knows of any good computer games that are Myst-esque. I am mostly interested in puzzle/adventure games. I really am horrible at playing games involving me having to kill something before it kills me (too stressful) but if you know of any good game, even if it isn't an adventure/puzzle game, let me know about it.
And no...I am not interested in getting sucked into WOW or anything...I do have a PhD to work on after all (which requires actually going to work):)
Here's a review of Portal. I finished it this weekend. It's a quick game, you can run through it in about 4 hours. But it's fairly mind bending. When you finish, there are advanced bonus and challenge levels you can play as well.
Not technically a first person shooter because you don't actually have a weapon, just a device that shoots portals. But it's a slick puzzle game with an interesting story that unfolds. You're basically cast as a lab rat in a testing facility with a H.A.L. like computer guiding you through. Hard to explain, just gotta see it in action.

Goldfarb’s power source is about the size of a pencil and contains a special catalyst that causes hydrogen peroxide to burn. When this compound burns, it produces pure steam. The steam is used to open and close a series of valves. The valves are connected to the spring-loaded joints of the prosthesis by belts made of a special monofilament used in appliance handles and aircraft parts. A small sealed canister of hydrogen peroxide that easily fits in the upper arm can provide enough energy to power the device for 18 hours of normal activity.
Awesome... not sure how commercially viable, given the manufacturing tolerances required and so forth, but extremely cool nonetheless...
