GPP

Handed in GPP, though we had a bit of hard time trying to settle everything, and allocating the work...its completed. As i was sick, my teammate,liu yi helped me out quite a lot and agreed to do most of the GPP, since its his idea in the first place. Anyway, we decided on the book stand that automatically support the books on the bookshelf,even after any books are being taken out of the bookshelf,the bookstand will automatically withdraw,so that it still can function as a bookstand and the books will not fall down. I've thought of the design,suppose to be our first draft, still uncertain whether it will turn out well~Lecture on tuesday was...i don't know...I was unfortunately sick and did not attend the lecture,was in the sick bay.
