New year is right around the corner. Here is a quick animation tutorial done on iPad Animation App - Doink!
Step 1: Create a colorful wheel using the vector shapes or free-hand
Step 2: Create a bicycle body with 3 frames, each showing flow of wind. To do that you can create small lines in each frame and then move their position to the left in subsequent frames.
Step 3: Finally create a composition where you add 2 of the above created wheels and then rotate them using the rotation properties. Add a text and You are almost done!
