Peter Johnson's first draft of "An Event Driven Approach to Modelling
Object Behaviour" included the following events:

>Selected
[...]
>Unselected
[...]
>Grabbed
[...]
>Dropped
[...]
>Collided
[...]
>Obj_obj_collision
[...]
>Default
[...]

I think we need some more events. At a minimum, we need a way of
triggering an event periodically, say "The smily face winks every
twenty seconds." I can also envision a variety of multi-user network
events which would be needed, like "another user Selected the object"
or "another user Grabbed the object" or even "another user collided
with the object," etc.
