Geo modding! Cool! Mouse your mouse somewhere and then press P on your keyboard to blow up the earth nearby. Note that I didn't translate the mouse position to world space correctly in this case, so the explosion is slightly off. Anyway, you'll see the world blow up and its pieces fly everywhere. Also bundled in this pack is creation editing! Press the spacebar to bring up the editor. Click a color in the toolbar on the bottom to select it. Then click in the empty space to draw that creation. Press space again to create it.
