Swan overlay

Show

Reverse direction Cygnets

Drag the body or head; the neck follows both. Drag the wing-tip ring to rotate and stretch the wing, the square tail handle to stretch the body, or a cygnet head to resize that cygnet. Drag each cygnet’s body to move it. Reverse direction mirrors the whole editable swan.

Snail overlay

Show

Drag the head to stretch the thick neck, the shell’s side and top rings to reshape its ellipse, or the square tail to extend the foot. Drag the diamond to scale the whole snail. Drag the shell or lower body to move it.

Peacock overlay

Show

Drag the head to stretch the neck and either square foot to pull a leg. The tail-tip diamond changes tail size, while the upper tail ring opens or closes the fan. Drag the lower diamond to scale the complete peacock, or drag its body to move it.
