Hey -graffiti. That's really cool. I don't know what layer mode you used but I find Grain Merge useful for this kind of thing.

That is kinda cool looking Rod. I had to try my hand at that to see if I could replicate it. Text, Stroke, Spread Noise on the both layers and rotate.
Grain Merge at 80% on a background of choice. Piece of cake! This would make a cool addition to the Logo Factory or maybe a script by itself called Chaulk Graffiti.

I agree

Here's my graphic novel version.

somewhere I saw a tut...long time ago, where they used bump mapping to give the graffiti a contoured look.

Good point. I tried a displacement map but it wasn't very good. Maybe I should have tried bump mapping.

I had some fun playing around with this generator to make some scenes,

Very cool!

Here's something I did today. I just couldn't find the right photo for the billboard. Even the stock that cost didn't look too great. The best I could do was to desaturate to make it somewhat interesting. I thought about putting a street light to the left. It's kind of bare over there.
