Did you want beginner ideas or advanced or just anything cool?
I've been hoping to use the time offset and duplicate layer to have a number of photos scroll across the screen. An efficient way to do that or some other application of time offsets and duplicates would be neat.
I was going to do a tutorial showing how to use a radial gradient in front of an object so the the Alpha-over in the gradient softens the edges... kind of dream like, or foggy. I was going to have the photos mentioned above fly behind this gradient so they fade in and then out.
Encapsulating the entire scene and using it as a camera control by animating the encapsulations origin and zoom.
I do a thing with character where I link the rotation layer of the front of the head with the rotation layer of the back hair so that things in front and behind the body layer rotate together.
I do all my drawing is synfig, perhaps a drawing tutorial of some kind.
Time of day or lights on and off using colour layers at different "amounts" You know... draw a daylight scene then put a .3 blue/black layer over it.
Well... that's all I have for now. Just brain storming. If anything else comes up I'll post again
I think a list of tutorial ideas is a good on in general, then if someone can do it, they can do it.
