First I will show you the easiest way in Photoshop to create even, concentric circles and after we will ad an inverted text to make it look hypnotic in a groovy kind of a way.
Pretty cool Photoshop tutorial, where we will add two text layers, one will be placed behind and the main at front. And I think you might really enjoy the final result, go for it and have fun!
This one for all the people who would like to have a go at designing a nice, clean and stylish looking flyer but don't have much experience with Photoshop.
