Hi guys! Maybe this question is sort of silly, but I thought it was worth a shot anyway. If anyone would know how to do this, you guys would. I searched a bit but couldn't find any info on this.

Is there any way in Photoshop to automatically "corrupt" a line to make it look like a natural cavern wall? Essentially, drawing a smooth line and then crinkling it.

Of course I could just draw this manually, but often you can get some great natural effects by using randomness in Photoshop, and I was just wondering if there was some technique I didn't know about, or if some technique could be devised.

This is basically what I am wondering about:



Any thoughts?
