Collaging
I love using this with classes as its instanteous art, its a quick way for people to make their own visions, its always 'unique and original' (people are very hung up about 'being original') and is FUN!

Kat's Paw's has an blog piece on collaging but many of the other articles I turned up on google I disagreed with their guidelines for collaging so here are my own~

Get a stash of magazines/brochures/catalogues/newspapers

A variety of starting media is best.

Get a A3 or bigger base sheet - using the back of cheap wall paper is good.

If not IMPROVISE! tear out magazine pages and tape into a backing sheet eg 3 x 5 magazine sheets make a large basis to work on. (This also results in more 'happy accidents' in the final collage.)

Give yourself a timelimit of 10-20 mins to flip quickly through the magazines.

Each time you see an arresting image or word or headline tear it out and put in a pile.

No sissors !*

Then give yourself 10-15 mins to paste down quickly onto the backing sheet.

No sissors - if you want part of an image tear around it.*

Use a glue stick as the least messy alternative.

When finished I like to play 'Private View' if I've been doing my collage in company and we go around admiring each one.

I find its best to put the collage up someplace you can see it near a desk or in a bedroom so you can contemplate it at leisure. They often have surprising insights into your current foibles, obsessions, and interests.

*I've found it helpful to ban sissors as I've had people sit for 5 mins cutting out something 'perfectly'. Squishing perfectionism is one of the delightful by products of collaging.
