XiB Circles is an app to show the patterns for building various circular shapes (circles, spheres, ellipsoids, cones, donuts). I added a new shape for the Windows 10 version of the app for the building of funnels. I thought this would be really cool for building some floating island cities. I also made it so you can control the amount of bend in the funnel. I haven't published an update to Windows 8 version yet as I am still trying to fix a bug with the preview.
