Can You Guess What These Are?

I am very excited about the future. This is a time in history when our technology is actually running faster than we can figure out what to do with it. So what do you think these are? Pens?

Some kind of tripod devices perhaps? Or how about some kind of microphone or web cams?
These devices are going to replace the laptop computer. They project an image of a keyboard. All you do is type on the image and it becomes your processor.
The light interprets the motion of your fingers and reacts as if you are typing on a 'real' keyboard.
Here's another version of the same idea. It makes sense. We've been using similar technology for a while. Think of the waitress who taps on a computer screen to process your bill.
This device makes use of blue-tooth technology to accomplish the same task. I love where this stuff is heading. For the first time in history, technology is racing ahead of our imagination. I believe there is no limit to what we can accomplish if we will only free our minds.
