The collected works of merrillaldrich

From about 1994/5 I taught Architecture visualization in a lab of O2s with Alias PowerAnimator. I am old now, obviously :-) . Back around that time, maybe one gen before, I vividly remember a flow-based image editing tool (a graphic UI with modules you could plug together to make an image editing "program," like FBP) but I can't remember what it was called. Does anyone remember or have a screenshot of that tool?
