You may (or may not have noticed a link) on the TSS page http://www.physics.ox.ac.uk/sat/tss.html to a Quicktime movie provided by Dr Kym Thalassoudis. You are welcome to view it of course (note it's 1.5 MB in size). My only reservation is that I have not yet managed to confirm whether it got to me intact( Dr. Kym's email address seems to be incorrect [if you are 'listening' please contact me!]). I have not been able to view it on Unix/X11 platforms (xanim) or NeXT (NeXTtime); I don't do Windoze ;-) Public health warning over. If anyone tries it please let me know if it worked (ie what viewer/platform you were using). regards, -- Neil Clifford <n.clifford@physics.oxford.ac.uk> http://www.physics.ox.ac.uk/sat/satintro.html
