My hoarding habits are mostly just that I really dig the aesthetic. Even on a broader scale, mediums that have strict restrictions are very interesting to me. As someone who deals with quite a bit of sprawling and ugly (socio-technical) systems at my day job, it's refreshing to see something small, simple, and elegant. Makes it fun to start making, you know? In contrast, something like regular pixel art kind of stresses me out whenever I try, given that the increased freedom makes "good" an ever smaller target.
So far, it's been small demos I've made as a hobby and then promptly dropped, like experiments for a 3D textmode game (based entirely on CSS transformations) akin to Tactics Ogre back in 2018, and a textmode UI for a FamiTracker browser port I wrote around the same time. Next, I'd like to start illustrating and adding diagrams to my notes on systems—perhaps those'll end up becoming public some time? I'm sure I'd have a thousand things I'd like to do with each font if I found the time and energy, but honestly, I'm quite happy by just participating as a supporter :)
