The tip I heard, was to close your eyes and swipe the wand so you are angling it in, towards the centre of your face.
It gives a starburst appearance and opens up the eyes. I decided to give it a try today. It really does open up the eyes! It does give a slightly stranger appearance, as your eyelashes will now point toward your nose more, but it is a neat look. It did feel a bit weird as the mascara dried because my eyelashes don't normally point in that direction!
I tried to take a picture (blinding myself in the process) to show the results.
