Two Circles Merge Into Square and Rotate. White background (#FFFFFF). Canvas 1920x1080. Two circles (diameter 120px each): circle A red (#E53935) positioned at middle-left (200px left of center), circle B blue (#2196F3) positioned at middle-right (200px right of center). Animation (8s): 0-1s: Both circles fade in from opacity 0 to 1 with ease-out. 1-3s: Both circles move toward canvas center using ease-in-out, arriving at the same position and overlapping. 3-4s: Both circles scale down from 100% to 0% while a purple (#7B1FA2) square (size 140px) scales up from 0% to 100% at center, creating a merge-transform effect. 4-5s: Square rotates 45 degrees with ease-in-out. 5-7s: Hold rotated square at center. 7-8s: Hold final state. Total duration: 8s.
