The South Australian Motor Accident Commission has a message to send to people who disregard the speed limit: vehicle accidents cost lives. To get this point accross, MAC brought in Emma Hack, the artist responsible for Gotye's "Somebody That I Used to Know" video, to design the "Body Crash" billboard ad.
It's a little difficult to tell, aside from that one extended arm out there to the left, but this car is actually 17 people lying on and around each other, then painted to look like a wrecked sedan. Here's a close-up:
The group of bodybuilders, athletes and acrobats were chosen for their flexibility and fatigue resistance. The whole process from design concept to assembling the models to painting the car is available in video form over at If It's Hip It's Here, along with lots of behind-the-scenes shots. Link
Thanks for the clear up - I'll give it a closer look tomorrow!
