Searches all calendar events for a certain tag, then creates an Omnifocus task on the basis of that tag, removing the tag when complete. Comes in two flavors: a (slightly faster) flavor using bash command icalBuddy, and a (slightly slower) flavor in all AppleScript.
An Applescript I wrote to check a reminders list called "Groceries" for tasks - if there are some, add a reminder to Omnifocus. If the list is empty, complete any reminder tasks. Useful for if you share such a list with someone else.
Transparent Future is a theme I built based in part on the atebits theme. It uses Futura, because I love Futura, and emphasizes transparency and a mostly black-and-white color palate, with separation for projects & subprojects, and some nice highlighting.
