Since these are sequences, they should be in a format which supports the animation of image sequences and has a public-domain sequence animator. The NCSA (Natl. Center for SuperComputer Applications, U. of Illinois) HDF image format fits the bill. The NCSA HDF image format and image viewers: 1) support the animation of color image sequences 2) are available in source and binary for numerous system types (mac, unix, PC, ...) 3) are maintained and improved regularly 4) are public-domain 5) are available via anonymous ftp at ftp.ncsa.uiuc.edu (128.174.20.50) Paul O'Keefe okeefe@cs.buffalo.edu
