Top and side view?
Nah, just something that gives you depth of field, sort of 3D, but not that drastic.
Oculus?

#62And so this makes an interesting point, LED shapes are controlled by the mold makers, but when do we get just a flat thin LED and you can 3D print the shape you want on top? :-)
Make a trip to your local Michael's or other art/craft store and you can do it today. Silicon sealant to make a mold + liquid molding acrylic and you're off.

#63Neat!
Now, I'd like to see someone do something like this for solar panels.

Maybe, but then you've got the lag and pixilation. Seems to be a solution in search of a problem. Still nothing nicer than human eyes looking through good glass of a stereo inspection microscope. Really not even the eyes, but the same posture for hours on end hurting the neck muscles. I suppose you can get used to it, but with a wire bonder there is not much leeway in adjusting the microscope position. Then again, for a guy manually wire bonding LEDs in China, it beats toiling in a rice patty.
Even the USB microscope cameras are garbage. Much better pictures just holding a digital pocket camera up to the eyepiece.

Video microscopes work OK for inspection but for working under the microscope, the video delay and the lack of stereo vision are pretty intolerable. What would probably work better is a Vision Engineering eyepieceless stereo scope.
How about a stereo microscope hooked up an oculus rift?
Sounds good for a second, and then you realize that it's going to induce a conflict between your visual and proprioceptive senses that'll make it impossible to work at best, and probably make you toss up your lunch besides.

#66If this is the manufacturing process and its price, why are LED light bulbs still expensive? (Serious question.)

#67Isn't the word "dyes" the right one to use here? Instead of "dies"?

Led light bulbs are considerably more intense. It has to contain a power supply, heat sink, and more LEDs than just the one that gets put into the single led, and all that needs to be interconnected on a chip.

These are not the type of LEDs used in modern light LED light bulbs. They produce a tiny amount of light (maybe 5 lumens each, with a 60W equivalent requiring 800 lumens), don't work well with a heat sink, and aren't particularly efficient. Separately, a lot more goes into an LED light bulb than just the LED.
Here's a teardown with cost estimates for a recent 800 lumen Cree 60W equivalent, where they come up with an $8 Bill of Materials for a bulb that retails for $13: http://electronics360.globalspec.com/article/3212/cree-ba19-...
