Isto promete, dos meus amigos Neo-Zelandeses da Diatom Studio, criaram uma nova library para o programa Processing, um programa grátis para Windows, Mac e Linux, que permite, com essa Library, não só fazer objectos, como desenvolver novas maneiras de os criar(?)

Via o Facebook da Ponoko:
Diatom Studio, the folks responsible for the SketchChair project that’s been mentioned here before, have created a neat library for Processing called CodeThread. It can be used not just for making objects, but for developing new styles of printing. As Diatom says on the CodeThread page on Thingiverse:
“One of the things we love about makerbot in contrast to commercial printers is that you have complete control over every aspect of the print technique. We think there is a lot of opportunity to develop new printing styles with makerbots, beyond traditional solid prints.
We wanted to experiment with the materiality of makerbot prints by working directly in gcode with processing, so we made this small library that provides some simple functions for generating gcode commands, and prints a gcode file.”

Quem se lembrar do Blitz Basic, bem, isto é MUITO MELHOR!
Para carregar e correr Processing no Ubuntu Linux, é só:
-Fazer o Download da versão Linux, 
-Descomprimir para a pasta, 
-E depois de entrar nessa pasta, botão direito em processing, Propriedades, Permissões, fazer correr como programa.
-A seguir, é só ir ao terminal, fazer sudo su, entrar na pasta, e escrever "sh processing"
...Depois, vão aqui, e ponham-se a aprender:

É bom!

Spider-silk-producing silkworms to be commercially developed

By Ben Coxworth

Although cobwebs may seem very fragile when we see people like Indiana Jones crashing through them, the fact is that spider silk is an incredibly strong and flexible material. It has a tensile strength similar to that of high-grade steel while only being one-fifth as dense, it can stretch up to 1.4 times its relaxed length without breaking, and it can maintain those properties down to a temperature of -40C (-40F). Given that spiders don't secrete huge quantities of the stuff on a daily basis, however, what's a biotech firm to do if it wishes to harvest the fibers for use in human technology? In the case of Sigma Life Science, it's getting genetically-modified silkworms to spin spider silk.

Cleaner-burning cook stove designed for use in developing nations

By Ben Coxworth

Chances are that even if you own a propane camp stove, you've tried cooking over an open fire at least once. When you did, despite your best efforts, you probably ended up sucking down a lot of smoke in the process. Now, imagine doing that for every meal. For many women in the developing world, breathing in toxic smoke while cooking over a wood, kerosene or coal fire is part of their daily routine. Not only can it have a detrimental effect on their own health, but it also worsens local air pollution and (in the case of wood fires) deforestation. The Eco Fire Pot Stove, however, is designed to allow these women to cook while breathing clean air.
The device was invented by Adama Kamara, a natural therapist who was born in Sierra Leone, but moved to Australia in 1996.

Radical-looking RoundTail bike claims radically smoother ride

By Ben Coxworth

If you banged a pole and a hoop against the road, which one would transmit more vibrations to your hand? Given that the flexing action of the hoop would absorb some of the energy, it's probably safe to assume that the pole would give you a numb hand quicker. Well, Canadian cyclist Lou Tortola applied the same sort of logic to the frame design of his Tortola RoundTail road bicycle. Where most other bikes would have a rear triangle consisting of straight seat stays, chain stays and a seat tube, the RoundTail simply has two shock-absorbing joined rings.
