Since it has been incredibly useful to me over the last 1.5 years, and since I've made a few tweaks to it since then, I decided to release a new version of my file size viewer.
So I made a web page for it, as well as a Windows version, after realizing that there wasn't much going on in it outside of standard C code and OpenGL. I also fixed it so that it only redraws the screen when necessary, so its CPU usage is reasonable now.
...and to answer my question in the origional post: No, I shouldn't eat more motherfucking sugar. I may have written this file size viewer while high on it, but over the next few days, as I continued to eat nothing but candy, I became incredibly depressed. Fuck sugar.
