Now that I have display performance sorted out on my machine I tried 
the Balloon3D package from SM. To my amazement, it works! If I use 
world>open>Wonderland 3D I get the basic camera morph and the 
workspace. If I select the ground and use the menu to make it turn 
around - it moves! Smoothly! Rapidly! Yippee!

However, it seems you get TWO sets of morphs. Both workspaces will 
affect bothe cameras. Delete a camera and unsurprisingly I get roughly 
twice the rate of display. Delete a workspace and the other one no 
longer operates either camera...

Some mistake here, surely?
