IOgraphica - tracking mouse movements

I was surprised to learn that at Habré no one had yet covered such a wonderful program as IOGraphica.
What is it for?
In fact, it sketches all the movements of the mouse cursor, and draws a circle at the place where it stops, the larger the circle, the longer the cursor was at that place.
For example, 20 minutes of active browsing:



Or 3 hours of active work in Photoshop:


The background on which the “graph” of mouse movements will be drawn can be left white, or you can “photograph” your desktop with windows.

I personally don’t see any practical value from the program (except to find out which part of the screen the cursor is most often in, or which window / icon / something else you most often refer to), but it's pretty funny to play around. Especially interesting pictures are obtained after a long game of some kind of shooter.

In general, I advise you to download and play :)

PS: An early version of this program was called MousePath

PPS: There are versions for both Windows and Mac OS and Linux.

UPD: By the way, I found a bunch of pictures with this program: www.flickr.com/search/?q=iographica&w=all&s=int
