1) Find the photo you want to create. 2) Create and select a new layer. Using the Ellipse tool , figure out the size of each circle you need. Lay them over the original logo. 3) Press the Hide button on the layer for the original picture. Select the circles, and hit Divide in the Pathfinder window to separate the circles into individual segments. 4) Delete the extra segments by Direct Selecting them and hitting the delete key on the keyboard. 5) Select everything, and change it to a nice Twitter Blue. There you have it!
