This tutorial teaches you how to create a personal logo.
1. Create a new document (1000x1000 or so). Fill the background with any color and select the polygon lasso tool.
2. Randomly select areas around the screen.(tip: Try to keep the yoour selection area thin and tall to get a better logo)
3. Now duplicate the layer (right click on layer > duplicate layer) and flip horizontally (EDIT > TRANSFORM > FLIP HORIZONTAL) Move the layers till you get what you want. Merge the layers by pressing CTRL + E on the top layer to merge down.
