I think this is the same as the brush stabilizer in Krita.

LazyMouse in Zbrush was the first one I think? But yeah, this feature is not uncommon.

There's even a program called Lazy Nezumi that adds global mouse smoothing, rulers etc. to Windows.

This is so satisfying. These types of experiments are something I really love about the open-web, and part of what bums me out about how most social networks tend to throttle links. The dragging behavior is so intuitive – it's funny because usually if you create this kind of resistance in a UI it can be confusing, but in this context it works so well.

> this kind of resistance in a UI it can be confusing it's actually intuitive because it mimics a real life physical dragging of an object by a rope, which most people have a feel for. Skeuomorphism can be quite intuitive imho.

Skeuomorphs retain purely ornamental components of the thing it’s mimicking. If it was a graphic of a rope rather than a dashed line, or if it looked like the line was tied up around the thing in a bow, those would be skeuomorphic elements. But graphical interface elements always retain ‘some’ functional connection to the physical world and trigger ‘some’ abstracted existing metal model about how the world works. GUIs themselves conceptually mimic the idea of a physical space because it’s easier for people to reason about than a bunch of text. This is no more skeuomorphic than the reply button below the comment box.

Earlier quoted context omitted.

Is it allowed to modify the signature someone puts digitally on a document? Because that's what this does. Is that not an issue?

What makes you say the library is modifying the signature? (It’s not)

Given it a bit of thought (as I was also puzzled), I think the comment was about the modification compared to a normal way of doing it. So if I would normally write a scribble with angular lines for a signature, and it might be consistent across different places, this brush could smooth it out and modify what it might be.

Very nice! I love the way the leash droops from gravity when you give it some slack, to unobtrusively and intuitively show users what's really going on, how the control system actually works, so it's tangible and physical, not a mysterious unpredictable black box. True honest wysiwyg "direct manipulation", no invisible magic.

It reminds me of artist/engineer's Paul Haeberli's legendary and monumentally influential "DynaDraw" which he wrote at SGI.

DynaDraw: A Dynamic Drawing Technique (June 1989):

>Here's a really fun and useful hack.

>The program Dynadraw implements a dynamic drawing technique that applies a simple filter to mouse positions. Here the brush is modeled as a physical object with mass, velocity and friction. The mouse pulls on the brush with a synthetic rubber band. By changing the amount of friction and mass, various kinds of strokes can be made. This kind of dynamic filtering makes it easy to create smooth, consistent calligraphic strokes.

>The C source for the dynadraw demo program is available. You can save this onto your IRIS, compile it, and give it a try. If you're a Mac or PC hacker, you might be able to port this program easily to your own platform.

Lots more great stuff from Paul Haeberli on his "Graphica Obscura" page:

https://en.wikipedia.org/wiki/Paul_Haeberli

He inspired another artist/engineer Golan Levin to write an implementation of DynaDraw with Processing and p5.js:

https://editor.p5js.org/golan/sketches/cZPRgx6q9

  // This is a rudimentary p5.js 'port' of Paul Haeberli's
  // legendary and monumentally influential program "Dynadraw",
  // which is described at: http://www.sgi.com/grafica/dyna/index.html
  // Originally created in June 1989 by Paul Haeberli (@GraficaObscura)
  // Ported to Processing January 2004 by Golan Levin (@golan)
  // Ported to p5.js September 2021 by Golan Levin.
Golan does a mind blowing amount of amazingly creative stuff:

I love his Double-Taker (Snout) (2008):

http://www.flong.com/archive/projects/snout/index.html

He explained that and more in this Ted talk "Golan Levin makes art that looks back at you":

>As Joy Mountford once said, "The mouse is probably the narrowest straw you could try to suck all of human expressions through."

I also love "Rouen Revisited" (1996)̀, a "monumental" architectural visualization that Golan Levin and another artist/engineer Paul Debevec collaborated on at Interval Research Labs, which led to Paul's later work at USC:

Paul Debevec teaches and researches at USC and Eyeline Studios (powered by Netflix):

Paul Debevec's "Light Stage" was featured in The Congress (2013), in the dramatically riveting and technically accurate scan scene:
