Agree, I think having at least a screenshot is a must. Or even an animated gif if it's some interaction (e.g. see plug [1]) you're trying to present. [1] https://github.com/shurcooL/Slide#slide
You accelerate the mouse precisely in the points where I want to see the anomalies (when intersecting the table).
The object keeps sliding on its background surface as long as at least one of its pixels is visible, unless it encounters a collision that cannot be resolved otherwise. Once that's no longer the case, it pops forward (keeping the same spot under your mouse) until it is.
There are 2 other videos where hopefully you can see this happening. Or, better yet, you can try it running it yourself on Windows or Mac.
