There are a number of drawing iPhone apps available, but I think it would be fun if you could paste the picture you draw on a real wall, but virtually.
Draw a picture with your iPhone.
Choose the wall you want to paste the picture on.
Point and paste the picture. Resizing possible.
Share it with people on an online map.
Or share with only the person you choose. And if you want someone to go to a place (physically) to see the picture, just choose “local share” only.
This is just like an old bulletin board outside and might work well if you want to convey your feeling to someone.
The images can be seen through your iPhone just like usual graffiti from any angle.
Thank you again for the great photos, *momoc.
