I build "Freewheeling Apps" -- simple, low-maintenance programs that are easy to run and easy to modify to your needs. Check out:
Lua Carousel: a lightweight programming environment for desktop and mobile devices
snap.love: a little app for drawing charts using just rectangular boxes containing text and arrows between them.
broadsheet.love: a plain-text file viewer that renders text in multiple columns to use all available window width without letting lines grow unreadably wide.
driver.love: the programming environment for looking inside freewheeling apps, and making changes live while they run. Itself a freewheeling app I modify using a second, "meta" version of the driver.
