The design in the page is a removable 3D printed shower head. This is very useful, since the shower head sometimes are stucked with small particulates in water. Those particulates are hard to be removed due to the reason that the shower heads are normally fixed.

2. artistic/ beautiful:

It is a really cool robot arm design. The rendered picture looks fantastic.

3. pointless/ useless:

A bedroom sign printed by 3D printer. It has to be a relative large size to be printed. I think it would be a really pointless job for it.

4. funny/ weird:

This funny looking design is a tippe top. It just looks funny to me.

5. scary/ strange:

The design is a flash light mount on wall, it looks strange to me. It is kind of hard for me to follow why people would need this thing to be printed out. Or even need it on a wall.

I don't really consider myself a tinkerer, however, I think my roommate is a serious tinkerer. He always tweaking around stuffs that are broken in our apartment and tried to fix them by himself. The influence of corporate culture on tinkering is kind of negative. As the more corporate it becomes, more money concerns and legal issues brought up. Therefore, tinkering would made the individual or company having law suit troubles. I agree with the author's idea that tinkering would bring this nation back to track as it has been proven. Like Steve Jobs, his innovation was from tinkering, and a lot other inventors or innovators started from tinkering. Therefore, to continuously growing, tinkering is definitely an important point.

Video
Cooperation of people from different background is a great thing I learned from the video. His group has a really large diversity. I was surprised when the printrbot was on the screen. The cooperation idea would definitely apply to our work here. For instance, collaborating people from a computer science background with people from mechanical/ material science/ and etc. would bring this reprap come to life. Only depend on the mechanical engineering, none of the machines would work, and vice versa.
