Creative Trails is something I try to do when I get stuck or just can't find ideas and inspiration. A trail can last a few minutes or come and go over long periods of time. What's special about a creative trail compared to just casual surfing is you sometimes realise that you are in the middle of a trail after a few days or a week.
The whole idea of creative trails started really long a go when I read Twyla Tharps book The Creative Habit.
After reading it I setup my habit to be persuing a theme; it could be a color, a sound, a name or whatever but I started surfing the web around that theme to see where I would end up.
