The designer I researched, Joshua Brewer, has worked for twitter, and has created successful designs like the one below. This piece uses a Gestalt theory that in my opinion is the most effective one in any piece of design. This piece uses continuation because the branch is leading the viewers eye to the important information that the designer is trying to show. Continuation is when the human eye is drawn along a path, line or curve. This is very effective because it leads the human eye towards important messages that are trying to be sent by the designer. I believe this design by Joshua Brewer is very effective and successful because it appropriately utilizes the continuation method to create an effective and appealing design. This design also sort of includes some similarity because the circular shapes with the images inside of them, are all the same except for the image inside of them. The colors in the font also are very similar, meaning that similarity is also used here. Overall this design uses two of Gestalt theories in order to create a very successful graphic design.

A very common design that I know and like that follows a Gestalt principle is the Nike logo. The Nike logo uses the continuation Gestalt principle in my opinion, because you start looking at the top and your eye is drawn through the path of the Nike "swoosh". Obviously this logo is very commonly known and liked. I think the fact that continuation is used is the main reason for why the Nike symbol is popular and effective.
