Crazy Clock

Having grown up all over the world when I was a child (Japan, Oman, Israel, Germany etc...) I have learnt to respect many different cultures really enjoy visiting new cultures. Rather than have a load of boring text all about the places I have visited I thought some videos and slideshows would do it more justice.

Degree Course

Physics Masters MSci 1st Class Honours. During this course I learnt how to analyse data qualitatively, write concise scientific reports on my findings and solve problems using my acquired analytical skills. C++ programming in my third year was part of a computational physics course also covering how to give PowerPoint presentations. I participated in group projects, sharing the work load and presenting as a team. My specialities cover computational, device, space and communications physics.

Finally I thought I would share my first and only attempt at making 3D video using Terragen, DEM files, Virtual Dub etc. If you have a compatable browser the video should appear below. I did this during my first term at Uni back in 2003. Enjoy!
