mineConics is a web app serving as a guide for the creation of circles and ellipses in games such as Minecraft and Dwarf Fortress.
I added Google Ads, hopefully they don't bother any users. It was very easy to set up, the only real work was editing the stylesheet. It would be nice if people didn't use adblock, but it would also be nice if ads weren't obnoxious. At least Google Ads don't blare audio or invite you to "punch the monkey".
