ECrater

This looks interesting; it's a free store website. If you have things to sell, this might end up being a very good place to start selling 'em!

I haven't explored it much, but if there's much interest (heh), I'll write more about it.

?japanese? kids' marimba orchestra videos.
What these kids lack in proper technique they make up for in precision.
"Sabre Dance" is probably the best one to watch first.

Reprap: Wealth Without Money...

If these guys are successful, normal geeks like me will be able to build a machine which can build itself and other machines.  If the machine is versatile enough, this could greatly reduce the need for manufactured goods.  I wish them great success!

From the wiki at http://reprap.org/ :

A project to save the world...

...or at least to improve it. For more details see the main web site. However, here is a brief summary taken from the main site:

A universal constructor is a machine that can replicate itself and - in addition - make other industrial products. Such a machine would have a number of interesting characteristics, such as being subject to Darwinian evolution, increasing in number exponentially, and being extremely low-cost.

A rapid prototyper is a machine that can manufacture objects directly (usually, though not necessarily, in plastic) under the control of a computer.

The RepRap project is working towards creating a universal constructor by using rapid prototyping, and then giving the results away free under the GNU General Public Licence to allow other investigators to work on the same idea. We are trying to prove the hypothesis: Rapid prototyping and direct writing technologies are sufficiently versatile to allow them to be used to make a von Neumann Universal Constructor.

All good projects have a slogan, and the best have a slogan that reeks of hubris. RepRap is no exception. Our slogan is:

"Wealth without money..."
