Part A:

1. useful : Hanger http://www.thingiverse.com/thing:44433 The hanger is pretty useful just may be hard to print.

2. artistic/beautiful : ZigZag Vase http://www.thingiverse.com/thing:44153 A beautiful vase.

3. pointless/useless : Battery http://www.thingiverse.com/thing:27012 Although it's called "battery box", I do not see any useful side of this design. Well if it's large enough it could be used as a table.

4. funny/weird : 3D Catapult http://www.thingiverse.com/thing:32541 A catapult in a modern car shape.

5. scary/strange : Alien Head: http://www.thingiverse.com/thing:44825 A classic icon of movie industry.

Part B: Am I a tinker? Probably not. Just like every other Chinese kid, or I should say just like the majority of Chinese kids, I do not have a childhood where I can take apart of whatever I'm curious about.If I do that, it will be really a serious family event. No kidding. But, while I'm prohibited to do such "Scientific exploration", it seems that my father can "play“ with everything he wants. Just like he has been trained before, he can fix anything. Well now I know it's more like life experience than inventing. When I saw the final project David Kelly has with his daughter, my first thought was "now I know why we need to see this". I think, to invent, to be creative, you have to think out of box. Just like David Kelly united a group of people with different backgrounds, our class have students from different majors,which is really good. I think diversity is the key, which keeps the whole team creative.

I can recognize some features like COPY&PASTE, Creating File etc. I have to say that I'm really impressed by his demos. If I were there, I think I would definitely have recognized the importance since it's such an impressive work. This kind of work does not need any relevant knowledge to know it's greatness. It's just simple awesomeness.

Talking about Open Source Project, I think it's a trend. Sooner or Later, more and more people will start doing open source projects and more and more of services and products we are using right now will be open source. Just like you can not hire every single engineer in the world to work for you, for one project, the people you can find that are willing are limited, but if it's an open source one, everyone could be your potential employee then you could have "every engineer" working for you, which is definitely helping you a lot.

The most "famous" example of the use of 3D printer is probably the potential Futuristic Moon Colony Project(http://news.yahoo.com/3d-printers-could-build-futuristic-moon-colony-135300655.html). I think it's pretty innovative and of course really bold. But to be honest, I somehow think that may work, since we can not take every aspects into consideration but if the Lunar Colony or the Space Station has one then they can print whatever they need. But that's under the circumstance that the 3D printer tech has been really really advanced. Nonetheless, i think it's the right direction to go.

The second example I found is the open source Wiki Weapon Project(http://defensedistributed.com/). Basically, it's an open source project about 3D printable guns. If you have a 3D printer, you can just download the STL files and then print your own guns. I don't know if this is a riight way to go or not since we are in such a time that Weapon Control is a serious topic but on the other hand, if we can print a 3D gun that is strong enough to fire then we can probably also print our own Armors that are strong enough to protect us.
