So they are gestures?  Unfortunately I havn't seen this kind of interaction 
model work well for a mouse (however it works extremely well with pen-based 
interfaces such as tabletpcs and PDAs).  There is a lot of work involved in 
point->press->drag->release, and you would be limited in the number of 
actions to reduce the fine motor control requirement.  There is also a 
certain amount of commitment once a user presses the mouse button, thei 
either have to mentally find a "safe" place to release, or commit to an 
action.

This seems very similar to the icon proposal listed on the Appeal project, 
however that interaction model works off of mouse hover (or just mouse over 
with no time out?).  This is much better because it does not commit the user 
to an action until a click.

Cheers,
