Has anyone seen "Oculus", a webcam program for the Macintosh?

It has a mode where you can overlay text on the webcam images (such as date and time or a caption). The interresting thing is that it has a mode for setting different opaquenesses for the "text background". This creates a very interresting, professional looking effect and I can't seem to produce it with GD or PerlMagick (ImageMagick). I've seen other packages for Perl that offer something that sounds like it may handle opaqueness, but before I start filling my system with these modules, I'd like to find out if there's a way to do it with PerlMagick. I also noticed that PerlMagick doesn't have a "GetPixel" type of function for returning the RGB or Hex code of a pixel's color value. Is there a way to do this with PerlMagick?

Thank you.
