Being a blog post mostly written as a reminder so that I can remember how I do this when I change machine the next time.
- Use Alastair Tse's WebViewScreensaver (new window) because Gavin Brock's WebSaver (new window) doesn't come with any installation instructions and there isn't an obvious .saver file or similar to double click (and who needs a helping of feeling stupid when trying to just have a pretty screen saver appear.
- Go into Security & Privacy in System Preferences to tell OS X that you really really do want to install the thing.
- Add What colour is it? or Design Quotes Display to the URL list. Or whatever site is currently rocking your world.
