Innovative Design; Water Curtain Stop Sign

We were inspired by this innovative design (from a while back) that has been deployed in Sydney.

What do you do when truck drivers just don't notice the multiple warnings you've placed on the road? And then wedge their truck into a tunnel entrance causing massive traffic jams?

What some smart folks have done is, using a curtain of water and a projected image, put a giant stop sign smack dab in the center of the road where it can't possibly be missed. See it in action here - very cool!
