Leaked FAA Document Provides Glimpse Into Drone Regulations – Forbes.
Some restrictions, and operators would need to pass an FAA written exam only, to obtain unmanned aerial systems certification and to operate UAS craft pursuant to a new Part 107 of the FAA regulations. The written test would be based on the content of the Airman’s Information Manual (AIM) plus additional content regarding UAS. Currently certified pilots of manned aircraft would also need to take the UAS certification exam, but it is expected this would require minimal study due to their knowledge of aviation. UAS operators would also need to pass a security threat assessment by the TSA (required of all pilots already). Once that is done, the UAS pilot would receive a unmanned pilot’s certificate with UAS endorsement. For commercial use, an UAS craft would also require an FAA registration number ($5 fee).
The exam could be given by a designated pilot examiner, a certificated flight instructor, or others designated by the FAA. Examination would be required every 2 years.
Total estimated costs for the initial certification are estimated by the FAA at about $300 including exam fees and TSA threat assessment.
As interest in 3D has declined, sadly, RealD is potentially putting the company up for sale:

Potentially an interesting idea: Russian startup 3D prints custom splints and plasters — RT News.
There are other lightweight mold-able materials and plastics that can be readily formed around a limb too – while it takes 12 hours to 3D print a splint. This might be solving a problem that is better solved with other materials.
The augmented reality glasses use three-dimensional cameras that detect the structure and position of nearby objects. Software then uses that information to block out the background and highlight only what is nearest to the user.
