This Is The Coolest DIY Project On The Planet, And It’s Incredibly Simple To Create

My mind is racing! Where could I do this????? Very cool moss project.

You could paint your car.

lol ummm --- no ... I'm wondering what it does to a substrate like the finish on the side of concrete walls. Such as, would it deteriorate it?

I couldn't imagine it hurting concrete unless over a long period. It sure looks like it would make good camouflage.

Ohh yeah for sure - the cement blocks around the lower floor of my house are sprayed with one of those textured products that looks like little stone chips. I wonder if the mold would expand in there and make it crack. That is probably only ---- what?? Maybe an eigth to a quarter inch thick. I'd love to do something on one of my walls but can't afford to destroy anything.

I don't think it would hurt anything, either...pretty innocuous ingredients.   CuzMike's idea of painting your car is pretty cool--no one else would have a ride like that! 

If you know a mason he might be able to tell you.
