Here are a few of the abstract UIs that I asked my intern to build for
various LADSPA plugins: http://testing.samalyse.com/lad/plugin_ui/

He worked with the TouchOSC Editor, which was rather handy for this, although
the goal is not using such interfaces in TouchOSC.

Colors can help to group parameters which relate to each other. A certain visual
coherence can be given to the UI by simple widget placement. A certain degree of
compactness can also be achieved, especially for toggles.

But all this is highly experimental.
