Finally I managed to pull off a decent longshadow spinning animation Take a look at it:
You can create them on your own now: Just grab a copy of RealWorld Paint and : 1. create your desired object: 2. Be sure to create a base object layer on which the shadow should fall 3. modify the style of the required layer and add these steps:
A.step 1 add shadow (shadow size 2, density 100 and offsets 1 and 1)
B.step 2 add shadow (shadow size 2, density 95 and offsets 2 and 2)
C.step 3 add shadow (shadow size 2, density 90 and offsets 3 and 3)
4. This way you can add a long shadow by following this pattern. Be sure to add some more steps as you desire. Be sure to start the first layer with density less than or equal to 100 only otherwise the shadow will be very dark. Still you can add a darker shadow if you please!!!!
