1. useful: eStand for iPhone This little stand is the perfect iPhone dock. It's small, relatively simple to print, and has a smooth and elegant design. On top of that, one could easily make a derivative of it that included a hole for you to place the Apple dock connector to USB cable to make it a functioning dock.

2. artistic/beautiful: Alien Egg Vase I think this vase is incredible. Like most of the Math Art on Thingiverse, it contains many complex mathematical shapes. It is also rather abstract which is why I like it so much. I think it is really cool how the beauty of the design overcomes the fact that it is only one color.

3. pointless/useless: iPhone Mixer Attachment The iPhone mixer attachment is really pointless. Why would you want to every attach your phone to a high speed motor, especially one that is meant for food? Unless you are trying to use your iphone as a mixing blade, this is useless. Or maybe it is meany for taking videos of mixing food, that is if your iPhone survives.

4. funny: Minimal Surface Pencils Holder While this abstract pencil holder looks really funny, I think in reality it is also useful...that is if you like alien art. I am not entirely sure how one would go about printing this as it contains some holes that may have to be bridged. But all-in-all a pretty funny shape.

5. weird: Thing5 Whoever made this really wanted to confuse anyone who looked at it. The designer decided to randomly place things on a base and call it a day. I think that if you were to print this, it would just be a waste of plastic.

Blog 2 1.) I think that while not currently feasible, eventually we will be able to create (almost)self-replicating universal constructors. Currently, a few major tasks still remain. First, we cannot and probably will not be able to print integrated circuits. They are currently made in pressurized argon gas. Printing them is not possible, but it would be possible to use the printer with another type of extruder that effectively acted as a pick and place machine. Another issue is the metal. Any extruder hot enough to melt metal would most likely not be able to replicate itself. But if we were able to mely metal quickly we could potentially make many more of the parts on the machine.

2.) Wealth without money is the idea that currently, many comercial products are extremely expensive due to licensing issues. But if we could simply make whatever we need from raw material, we could save incredible amounts of money. Some problems with the idea are one, there are only a handful of materials that currently can be printed. Yet almost all products are made with at least a handful of materials. Also, currently the exact model of an assult rifle is posted on the internet. If you were able to print out the parts you could make a fully automatic ar-15 rifle which is currently illegal to purchase.

3.) I think the RepRap project will do one of 3 things. Either it will take off because people like us can spread the ideas and continue to innovate. Or it will simply stay where it is now and not improve very much over time. Lastly it could die off because nobody is innovating.
