Well, since there's apparently a quiet moment in discussion, I do actually have a thought on the topic I'd like to share.
Now, I'm not very familiar with the concept of Chaos Magic, but from what I've read in this thread, it appears to be something like meditation, free association and doodling, combined with drugs and rigorously searching for anything that could be called an effect of the magic. Apparently it was employed by at least a couple prominent artists in the past few decades.
I find the idea somewhat interesting, as it just happens that lately, I have once again gotten into meditation, free association and writing stuff on paper, in an attempt to focus on things better and maintain a mental state conductive to work. And, in my personal anecdotal experience, they do seem to work. After a tiring day, I generally feel better after writing in my journal before bed, and if I write a task down in a notebook, I'm more likely to complete it on time. Meditation might do something, or not, but it usually improves my mood. And there certainly are times when free association helps solve problems.
There are clear differences, but in some ways, those things appear to be similar to the exercises suggested in the salad days of the thread. Considering they're things I use and appreciate, I'm not surprised to hear that these chaos spells could appear to do some good to people. And it's really not that surprising a thing, anyway. If you strip away the magical explanations tacked on by people with a paranormal agenda, the core of the proposed ideas appears to be just focusing on a goal while allowing lateral thinking - and it's not really a secret that those are generally useful things to do.
