A tinkling symbol

I keep seeing these flour circles all over town, on Arthur's seat,my street etc.. not sure if they mark out a route or are some other secret symbol. Meant to blip them all but the rain got there first.

[late update courtesy of booty928 - these are markings of [url=http://en.wikipedia.org/wiki/Hash_House_Harriers]the hash house harriers[/url] which are not stoned birds, but an intoxicated runner's group around since the colonial days who scale cities in a form of paper chase race. Looks fun.. I think..?]

While on the topic of symbols I heard an interesting new psychological assessment method today. Want to try an experiment?

Visualise the following 4 things in as much detail as u can, size, shape, colour, texture, type, weight, etc...
1. A cube
2. A ladder
3. Flower (s)
4. A storm
5. Now picture them all together in a scenario and describe it. Where are u in relation to it? In it? Out? Etc..

If you leave a comment with the details, I'll reveal the result.
