Planar elastic domain
This application simulates a planar elastic sheet. While you drag some vertices, the rest of the mesh moves in order to lower its elastic energy.
Right click on the background to open a menu. There are two types if objects solids and holes, which you can add and edit in "Domain" mode. In "Selection" mode you can use the green "Brush" (brush needs to be in "select" mode) to select vertices. Mark selected vertices as "fixed" or "movable". Finally, in "Physics" mode you can drag the movable vertices around and the rest of the mesh moves like a rubber sheet. Since there is no friction you always need some fixed vertices.Try the following:
