Fun fact: spiralling staircase is the opposite of the rotation to create perspective using scorlling here, as they're creating rotation with parallax - perspectiveless - scolling here.

Except it's not scrolling since it changes perspective, thus it's actually a looping animation (:

http://www.youtube.com/watch?v=9RwVZq5kCUY if you watched the other vid you'll see they do something very interesting with a spiral staircase, only that the angle is completely wrong for the sprites....this one is the original with an angle more on accord with sidescrolling sprites
ah that was the one i was looking for D:

Not to resurrect an old thread but that's exactly what I am doing.  Here I found this neat little tutorial about how to do perspective scrolling.  http://www.maidenart.co.uk/perspective-scrolling.html

Furthermore the way I was going to do my effect of changing perspective(Not really a change of perspective really but simulated) was by using prerendered pixel textured(of course it wouldn't be perfect) 3D cubes that were animated rotating from its center at 180 degrees.  Afterwards I would assemble all 60 or so images in a gif and then import it.  As the character runs across the game field the buildings will rotate(which is just changing animation frames) based on the players current position.  The further the player was from the start the more the player could see of the other side of the building.  However when I told a friend about this idea he asked how I was going to allow the player to see the tops of the buildings and my answer was I have no idea.  Currently I can't think of a practical way to do that.  You would have to have a bunch of combinations for each side being turned horizontally and vertically.  So just for one turn you would need multiple animations that show the building as you are looking down on it as well as up.  Though this could all be solved by having super tall buildings that the player cannot see above.

Anyway I'll probably do something like this for my game, that best thing about it is it can still be parallax scrolled.  Let me know what you guys think?

Furthermore let's continue this riveting discussion.

Sorry for digging this up but I figured it would be good to keep this in here since its related.

I was wondering if it would be possible to take a top down shmup facing upwards and rotate the perspective to a side scrolling shmup facing right entirely with a scrolling map. It would get pretty complex since the camera would have to scroll as well as rotate so the plane could end facing the proper direction. But I assume this would be done using a 5 point perspective?

I am sure that it CAN be done. I know they did it in old Looney Toons cartoons, not precisely from top down to sidescroller but there was a lot of complex perspective change like that, the bad news is I have no idea of what toon features it.

I am sure there is some of that in the 2D Star Wars the Clone wars. http://www.youtube.com/watch?v=CiudMz223PM&feature=related I believe there is something like what you want to do from 1:30 and a few moments later when the ship crashes EDIT:http://www.youtube.com/watch?v=ThY_F8Z7u08&feature=PlayList&p=C413DBA01A38A7E8&index=9 here is a long ship fight http://www.youtube.com/view_play_list?p=C413DBA01A38A7E8 here's a playlist of all the episodes, I think they employ it a lot when there are ships flying.

Also remember the Gunlock vid I posted earlier http://www.youtube.com/watch?v=xmfxMA13O-I&feature=related you should probably check the whole game since they do it all the time.
