How cool is this? This image of a car crash was created by Australian artist Emma Hack using paint... and people.

There are 17 bodybuilders, athletes and acrobats curled up on top of each other to create the image of a crashed car.

The piece, 'Body Crash,' was created as part of an Australian road safety campaign sponsored by the Motor Accident Commission.

Check out the making-of video below.

It's quite an achievement - Hack (who also did the body paint in the video for Gotye's 'Somebody That I Used To Know') spent 18 hours painting and arranging the figures to get the final image just right.

But it's not the only project of its kind that came out recently.

These images of human motorcycles were created by another body paint artist, Trina Merry, as part of an ad campaign for a motorcycle show in the U.S.

The amount of work that went in to each image is pretty incredible: the dirt bike above took 13.5 hours to create.

The cruiser took 15 hours.

And the speed bike took a full 18 hours to complete.

Check out a making-of video below:

The project started with rough sketches and lots of planning.

Merry gathered a group of yoga instructors, flexible dancers, circus performers and aerialists for the project. They all had to stretch out carefully before getting started on their poses.

Once the poses were worked out...

There was a lot of body painting to do in order to get to the finished product.

It's a pretty impressive achievement.

But it's probably worth pointing out that the finished product still amounts to a poster of a beautiful woman on a motorcycle.

Apparently, some things just don't change.
