This is a series of tutorials focused on neuromorphic computing and Spiking Neural Networks (SNNs) from the ground up. Through a mixture of code, interactive visualizations, and descriptions, it covers the basics of implementing and constructing SNNs

I really like these interactive visuals, they make things concrete and engaging. For this one, after I click on "Add water" I'm a little confused about where on the chart on the right I should be looking and exactly what it means. I understand that each spike corresponds to an "Add water" click, and I think the amplitude corresponds to the current water volume; is the x-axis of this chart time? I think it would help to add that. I guess I'm wondering which point on the chart represents the current water volume -- I would guess whatever the value is on the far right.

Actually, I just noticed the dotted line going from the water height to the chart value. That helps. I just didn't see it initially. I think it'd still help to add axis labels though, and maybe include a notch/label on the far right of the chart saying "current point in time" or something.

"The size of the hole (which we will leave fixed so won't refer to by any variable)" - should this be the initial size of the hole?

As you described it above, Tau corresponds to the stretchiness of the hole. Is is also true that Tau impacts the amount of water added in a single "Add water" button click? I say this because the amplitude in the chart seems higher for smaller Tau; not sure if this was intended though.

I like this part. Super easy to understand.
