Instructions for editing it to use your own search term: 1) Open the .qtz file in Quartz Composer. 2) Make sure that none of the patches are selected. 3) Push the keyboard shortcut command-1 (to open the Inspector). 4) In the field titled "#", type the hash tag you wish to search for (e.g. "@inklen" to list my twitter mentions). 5) Push return.... that's it. You can also edit a number of other parameters, which should be fairly self-explanatory.
