Preparing to move - cleaning flat

We started clearing our stuff. I found that we have had few boxes left unopened in store room since moving to this flat few years ago. I wonder how long will it take for me to clear all of them. But it is like treasures discovery when clearing the boxes one by one. Here is some of our memorable stuff and some to be reluctantly thrown away.

In 'Z' sequence from top-left to bottom-right;
1. First pager about 9-10 years ago, now obsolete;
2. CD case from the NTU's alumni office;
3. NTU 2000 millennium celebration's key chain, the millennium means more than a celebration for us;
4. Uluru's geometrical tools (since secondary school?);
5. Dunno what? Another souvenir?
6 & 7. Some puzzles;
8. Ultra old spectacles;
9. Uluru trying out the ancient spectacles, still workable :p ;
10. Uluru's honours year timetable in NTU;
11. Uluru's society, membership, name, etc... cards, some from a decade ago.
