Description : This is a very small lib that with tweaking can do some really neat things. I have a demo that you can download which has complete source and a simple example.

 Excellent effect, very nicely presented.  I'd already given the gallery image a 5/5.   ...and thanks for the preview!

 Cool effect!I was experimenting a bit and got it to work with other width/height values than 640x480, and the sprite is now 1 unit away from the camera so you don't have to make the CameraRange near# value as small:Global l_surface=CreateSprite(camera)Global width=GraphicsWidth(),height=GraphicsHeight()SpriteViewMode l_surface,2PositionEntity l_surface,0,0,1EntityOrder l_surface,-100ScaleSprite l_surface, 1, 0.75Global l_texture=CreateTexture(width,Height,1+256)TextureBlend l_texture,2ScaleTexture l_texture, (Float TextureWidth(l_texture)/Float width),(Float TextureHeight(l_texture)/Float Height)EntityTexture l_surface,l_textureEntityAlpha l_surface,.3Function l_setAlpha(alpha#)      EntityAlpha l_surface,alpha#End FunctionFunction l_update()   RenderWorld   CopyRect 0,0,width,Height,0,0,BackBuffer(),TextureBuffer(l_texture)   End Function

 Cool :)Has anyone tried adjusting this for multiple cameras by the way? e.g. 2 player split screen. Guess its a case of having x2 sprites one per cam etc.

 I just noticed I was hosting this at one point, but a lot of links died when I changed web host. I'd be happy to put it back on the original link if you want to email it to me, daaan.
