I stumbled on these early screenshots of LiveCompare recently:

They show how Radon (codename for the new generation LiveCompare) grew out of our NetProcess toolsuite and in particular how the 'LiveCompare Studio' module (which we refer to affectionately as the 'woofer' because of its WFR filename) was originally prototyped using the LiveModel flow chart rendering control.  I for one am not sorry to see the bright colours get replaced with LiveCompare's pastel shades.
