This one even does not work as an obj file. It is a simple cube and a ball prop.

Delete the txt extension and leave is as pp2. Import the pp2 into Poser or put the pp2 in some prop library and load it. You will have a ball and a cube because it is a valid pp2 file.

Now take again the CubeBall file and rename to CubeBall.obj. Import it in Poser or any other application. Do you see now a nice cube and ball or something strange ? Depending on the application you use to import this fake obj even can make your app crash. Poser at least doesn't crash.

Stupidity also evolves!
