I missed the earlier discussion, sorry. >> With a 3d space sliders can be made to do some amazing things.

You just need to start with at least one point on the widget. In fact it could work well with a mouse too. The widget could look something like a circle with a cross in it. When you click and drag up the cross opens up and when you click and drag down the cross closes. This would provide a circular image with a rectangular/slider single axis movement. >> Why constrain ourselves to a concept we know is a pain for the user if >> it >> is also gonna be a pain for the developer to implement?
