Open in TextMate
Open in TextMate allows you to open the current folder or selection from Finder as a TextMate project. There are a few scripts for this, but this one is the latest iteration and it comes with a nice icon that fits will into the Finder tool bar.
Henrik also provides tool bar items for Open in Terminal and Glob Select which are definitely also worth checking out!
