This kind of thing has been done for years/decades, and is used a lot in industry already. I know of many companies that are taking their CATIA or NX models, and visualizing them in VR or CAVE systems. You can even buy software which has been written to solve this problem for you ... you just buy the VR hardware, load your model in, and you can manipulate it. For example, here is a video of something that you can go and buy right now ... http://www.worldviz.com/industries/cad ... the sample video uses a stereo projector and a wand, but you could easily use Leap Motion, a full motion capture system, or whatever hardware you have.

The gestures he shows in the video are also very primitive, and did not appear very intuitive. He spins his hand in one direction, and the model rotates about a different axis. Just spinning a model around is not really designing anything, it is just a preview technique. And in some ways, using a mouse could probably be less fatiguing and more intuitive. The real holy grail is addressing the problem of creating models from scratch. And making them accurately so the designer gets what they want, and typically designers will probably want to use a keyboard so they can enter in exact dimensions. But this is not addressed in the video, but I'm sure everyone will think that is what they actually can do.

But because Elon Musk is doing this and now you are seeing it in the popular media, he must have invented it, right?

If you want to see something really cool, check out this system, the Lockheed SAIL, which was done years and years ago ...

My T40P has this wierd problem with its motherboard where devices will some times show up as 1.1 and some times as 2.0 devices.

For example, plug in USB hard drive under Windows XP and it detects the drive as a fast 2.0 drive. Pick up the laptop and by flexing the case all of a sudden the drive is un-detected and then you get a pop up saying that the device is a high speed device on a low speed controller.

I ran the MS USBView tool and you can see the device hopping from one hub to another, its really wierd, and is caused by flexing the case. IBM said they will replace the motherboard for this, just haven't had time to do it yet. I've seen other people discuss it on forums as well.

This problem is nothing to do with SP2 - it happened before I upgraded, and also probably Linux too, since it is hardware related caused by flexing the case.
