Here's a neat concept from the folks at SoKrispyMedia. Chalk Warfare, in which combatants draw their weapons with chalk and then fire away. So, for example, if you want a machine gun, you draw a machine gun. And if you want to trump the other guys machine gun with a rocket launcher, get sketching.

Take a look at how it works.

Of course chalk warfare only works when you have the benefit of post-production. So we don't feel so bad about how when we used to play war as a kid we had to use plastic guns or our fingers.

So what do you think? Would you have the drawing ability necessary to be a good chalk warrior? Or would you end up a chalk outline?
