It is easier to see the three dimensional structure in a MPEG movie of a rotation about the z axis. This movie was also created using TIPSY.
Here is another movie of a halo collapse.
Tipsy, the adaptive mesh code and the simulation data are all freely distributed. The data has not been left on an anonymous ftp server as we feel its strengths and limitations should be discussed with any potential user. Contact Hugh Couchman, email@example.com, if you wish to use this data. __________________________________________________________________
