A four year old could have made that…
Send this print out as an invite to your friends to come over to your house for a ‘Factory’ party (Andy Warhols famous loft where artists commiserated).
Put random supplies all over the house and let your guests know that whatever they do must be easily removed from your home (leave a canvas out for them to paint on, altars for them to hang things, the more random the supplies the better the outcome). You may also ask guests to bring junk items from their home to add to the mix. Play 6o’s music and if being hosted by a couple have one of you dress up as Andy Warhol and the other as Eddie Sedgwick.
They idea is to get the most insane ridiculous piece of ‘art’ that some one can get away with …a bathtub of rubber duckies, a sculpture of soup cans, etc.).
