I wrote a little cl script called 'do'. It requests a name, description, and tag list for anything I think I might like to 'do' in the future. For instance:

  Name: Gideon Series
  Do a series of new-primitivism photos, Goldsworthy 
  pieces, except environment is cheap motel room. Bible, 
  towels, bad art, curtains, etc.
  Tags: art, medium, moderate

Then I can forget the idea. When I feel the need to begina new piece, I can ask for ideas about art:

  > do art

And one will appear for my perusal. 'Medium' and 'moderate' refer to difficulty and time required.

  > do short easy

Helps to fill spare moments, when I don't have much attention to spare.
