Update (18. 3. 2022): the concept works quite well, but needs to be connected to some other app that automatically tracks productive time, since adding dots manually (even via a script) adds too much overhead. I’ll no longer be updating the image, but the post stays up.
With the end of the summer holidays and the beginning of a new semester, I’ve been thinking about clever ways to trick myself into being productive.
There are, of course, a bazillion apps, services and techniques to help with this, some of which I’ve used in the past. I felt, however, that none of them captured the hours of work I put into whatever I deemed productive in a meaningful way.
That’s why I came up with the concept of a productivitree. Here is mine:
The idea is simple: for each productive hour, I fill in a dot, with the color depending on the type of activity I did (education-related dots are blue, others are black1).
Although this might not be a groundbreaking discovery in the field of procrastination, I wanted to share it anyway, since some people might find it useful/interesting.
Generating the image
The above image was generated using weighted stippling, which is a technique where a given image is converted into a set of points of varying thickness (see this paper if you’re interested in the math behind it).
I used the StippleGen program when generating my image. It should run on any major operating system and has a pretty straightforward UI, exporting directly to SVG.
As for updating the image after being productive, I created a simple script that does this automatically, selecting the one that is closest to the center.
If your system prefers dark theme, the dots will yellow/white, since the colors are inverted. ↩
