Loved this. They are also creating a tool for those actually designing rounds:

"Like what you saw? Send some social love and encouragement for Venture Makr: a full editor to create your own rounds with custom valuations and equity distributions. Turn the knobs on your own creations and see how scenarios might unfold differently."

Author of that thing here, glad you guys found it helpful!

There's an original HN thread with some discussion on it around here somewhere, but if you have anything on your wishlist, let me know!

Very cool visualizations. It would be interesting in the last interactive one (illustrating liquidation preference) to see how a liquidation multiplier affects things. I'm a little unclear on the calculations for the preferred stock holders continuing to get money after their liquidation preferences are fulfilled.
