3D-ized 2D, a sort of challenge or a how to question...

[madscijr]

I was thinking and wondering how one might skew 2D Space Invaders to look 3D, like 


and also have photoreal stars scrolling in the background, like 




simularly skewed, playing in a loop. 
With the scene sometimes flying through space dust clouds, like 






Just something I imagined. 
The actual game play would similar to the classic game except the aliens might move in more interesting ways, like have the entire formation move around at times or have rows or columns of them move on & off screen, and let the player fire 2 or more shots. 

But mainly I'm curious how you would skew the 2D to look 3D and do the 3D scrolling and moving through clouds (which could at times obscure the view)... The game itself would be programmed and behave like a 2D game though.
