Here's a video presentation of my attempt at a compact visual syntax for Haskell as part of the Glance project. Video: Slides: https://docs.google.com/presentation/d/1MC37OSCooOS9Kwkg8vj1AeIKTV4e2pqH3ijcBnlq1iw Feedback on the project goal and strategy, and the high level visual design (e.g. using indentation, the topology of the nodes, etc.) would be especially useful.

(I just recorded a video of the GP thing, attached. I'm dragging a slider in the top-right corner. The transformation is pretty superficial, kinda tacky. You show something more substantive. But I think the intents are interestingly aligned.)
