After reading "What do prototype prototype", I remembered that I mentioned a project during class a while ago, that plays with light and the transformation of every day objects . I realized, I forgot to post it. Here it is.

Also here is the link to Stairway to Heaven, a short film by film  maker Erroll Morris. The film is based on the life and work of  Temple Grandin. Grandin  explains in the film the relationship between her autistic condition and her ability to design. Here is the link. Enjoy!

## Make up reading – chapters 7-9 in Code

List and describe 2-3 things you found interesting for chapter 7-9. Or describe what a UPC code is and how it works.

I've often wondered what the weird Roman numberals are at the end of a movie during the credits, i.e. MCMLIII. Chapter 7 it explained that this is simple the year in which the picture was made. Now I know :).
I found Chapter 8 to be rather confusing. I remember discussing the powers of ten concept in the seventh grade but it definitely made more sense then. My teacher used the example of time (based on 60) and our currency (based on 100) to explain the concept. When the author started talking about cartoon hands it was definitely more difficult to grasp the concept. Chapter 9 goes into depth about explaining the UPC. The UPC (Universal Product Code) is a visual display of binary digits used to identify products. It is made up of 30 vertical black bars (and white gaps) varying in width. The black bars and white gaps vary in width and that space is represented by a series of bits. In total, the UPC has 95 bits. The bits can be grouped and read more easily – the first three numbers are the "left hand guard" followed by a series of "left side digits" (6 groups of 7), followed by the "center guard", and then the "right side digits" (again, 6 groups of 7), and finished off with the "right hand guard."
