Paper Globe

While looking up the butterfly projection of the world, I noticed that the flat edges would be easy to cut out with tabs and glue together as a 3D globe.

It's not the prettiest globe, but easy to make. Certainly truer to a three-dimensional world than the Mercator projection.

Search online. There are lots. Here is one I found on the xkcd forums.

Make sure to leave enough space around the edges of the page to cut tabs.

Cut tabs as shown.

Use tacky glue to fold the tabs under and watch as your globe takes on round-ish dimensions!
