I had to make a logo for a college assignment, and had a bit of fun messing around in Illustrator. 

I made this out of my initials, J and A.  I started with a black background, and then to make the J I made a white triangular shape with half an arrow blacked out. I then duplicated this shape and rotated into make the A. Hopefully you like this more than my name in New Times Roman, as I will be using this to watermark my work from now on. 

This was an earlier idea, but then I searched logos with eyes in it, and found a near infinite amount. Wanting to be slightly more original, I scrapped this idea.
