Richard, ideogram.pm is part of GBrowse. I fact, I see it here in the  
GMOD CVS repository:


Sheldon McKay (mckays at cshl.edu, is probably on this list) at CSHL did  
some more work on this Bio::Graphics glyph after my initial  
implementation (for the HapMap installation at http://www.hapmap.org/ 
cgi-perl/gbrowse), fixed some color overflow bugs and added another  
ideogram-like glyph to GBrowse (heat map). Sheldon may be able to  
help you if you want to add some more functionality and/or create new  
similar glyphs yourself for displaying CGH data.
