In an mk5, just pause, pull out filament, shove new filament in, and
hit pause again. I did it during an infill to avoid perimeter ooze.
Not really an effect I crave all the time. I'd rather wait for dual
stepper extruders to emerge like the Ultimaker.

Democracy App. Communications, an Inalienable Right
Can we use 'citizens arrest' for the entire governing body? There is significant evidence that the leadership has made choices to the detriment of the people and used their power for personal gain and protection. This should also apply to thief business contacts have helped them obtain and a use that power.
Look at how we use Facebook. A change is in the air. Try blogtv. Get an account and use it to communicate and organize. Technology empowers us all to have a voice.
We need a voting system to have direct democracy. This can be as simple as an app. With 3 billion phones in service and 4 billion more expected to ship in the next few years, everyone can have a phone and use it to vote. This means that anyone can vote on any issue and anyone can introduce a new bill. Communications should be an inalienable right.
I know of an app called Congress that has representatives contact information and voting history. This is a good start, but decisions can not be left to a minority of elite individuals. They will always be bribed by lobbyists.
Can anyone begin work on an application that I described? I have Burgundy learning android programming, but I would like to see this happen quickly and for all platforms. It should be able to collect and process up to 7 billion votes and display the results for each bill.

"We made more complex, tinier holograms that enable us to achieve 10 times the separation angle between beams – important for applications – and 100 times the orbital angular momentum on electrons," explains McMorran. "This is possible because each grating in our hologram produces multiple beams with higher diffraction orders containing proportionally larger amounts of angular momentum."

Broken Cyborg (was Re: "Transcending the Human, DIY Style")
We're in it for human enhancement, synthetic biologies, longevity, nootropics, software, prosthetics,
As you can see from the x-rays (most clearly in the fourth picture), I have a titanium full knee replacement with a broken rod that takes the place of a tibia.
http://picasaweb.google.com/technologiclee/ProstheticImplantXRays#
History:
This started as an ostogenic sarcoma in the tibia at age 15.
http://www.google.com/search?q=ostogenic+sarcoma
There was a year of chemotherapy.
The knee was replaced with a cadaver bone that was shattered a year later.
The knee was then replaced by the hardware shown in the x-rays.
I had good mobility for about 10 years. Then one day the rod just broke in mid step.
This is probably due to metal fatigue.
The rod has been broken for over two years now.
My options:
I have not found a doctor that is interested in attempting to replace this hardware yet. Maybe my new health care will bring help this year.
At the time of the surgery this was a fairly new procedure. Since then it has become more commonplace, but it is still a fairly complex surgery. There would be no guarantee of improved mobility and the possibility of infection, amputation and or death.
Honestly, I do not think that the procedures currently available are what I want.
I would like something more 'natural', like having a replacement knee printed by a bone printer and installed. There is already nerve, muscle and skin damage, so for an ideal solution, stem cells would be used to regenerate the damaged tissues.
http://www.google.com/search?q=bone+printer
What would be better is to augment the knee with robotics internally or as an external brace, like they are working on at MIT Leg Lab.
http://www.ai.mit.edu/projects/leglab/
Best Solution:
Now that the future is here, the hardware and software for 'medical nanobots' is almost ready. What would this entail? Removing the hardware. Directing stem cells to sites of damage and allow them to organize into appropriate tissues. This means that a 3-D model of the leg would be made and a set of instructions prepared to direct the robots. This is the next 'Killer App'. I would like for this to be the start of a thread about medical hardware and software in terms of radical reconstruction. What is the best medical and machine control software available to base this off of? For a start there is EMC machine control software and Google Body.
http://www.google.com/search?q=medical+nanobot
http://www.google.com/search?q=EMC+machine+control
http://www.google.com/search?q=google+body
Do you remember the 'tissue processing' scene from the movie The Fifth Element? Watch the hardware and software in this clip. This is the goal. This is something that is coming together from every corner of research.

Trans-dermal Implant:
During the chemotherapy I had a "port (or portacath)" installed and later removed.
http://en.wikipedia.org/wiki/Port_%28medical%29
In terms of size and considering modern electronics, that is enough volume to place something like a low power processor.

Did you see the new spray on skin technique??
