Gigatron That effect curtain is not what i'm looking for, but the transition .FX looks cool!! <img src="{SMILIES_PATH}/icon_e_surprised.gif" alt=":o" title="Surprised" /> .

I don't know if you can work on this again to improve, maybe start a thread showing this and see how people is interested and if worth it.

In case you are able to work on this again, here are more ideas:

About Transition 0:

The squares with a big size looks ok, but if i try to use them at small size like 1x, 2x,etc.. you can see the pattern :S

Now they appear with some kind of seed. Will be great some option to appear ordered in horizontal/vertical/diagonal to the opposite.

About Transition 1:

The circle effect is good but is a ellipse , i guess is because i'm using a 16:9 and the effect stretch to the window size instead of keep a 1x1 circle ratio.

Also will be great have this type of transition for squre/rectangle/rhomb/bar(horizontal\vertical).

General:

When the effect is finished, if i restart the layout not start again. Maybe this is more a problem of my project config but i can't get it, any idea?.

Oh yes,it's possible. I think you can draw circle square fade or what you prefer shaders with for screen transition.Years back,I started multi transition fx found hovement.com/how-to-measure-for-curtains very handy in helping deal with the curtain provisions.I understand that effect curtain is not what you are lookingfor,but I'm sure you might find that link helpful.Thank me latter.
