In swirl {marrayInput} page
http://www.math.mcgill.ca/sysdocs/R/library/marrayInput/html/swirl.html
it suggests the raw images are at
http://fgl.lsa.berkeley.edu/Swirl/index.html. This server seems to be
unavailable right now. Does anyone know if these images are available
anywhere else?
Thanks, Dave Waddell.
