Transforming a retangular image into a circle

I have been trying for a while to turn a panoramic picture I have into a circular picture but have been failing badly. (using PS CS2)

The picture I have is of a row of houses in a street. What I would like to do is somehow fold the image into a circular image, having the pavement (sidewalk) run around the outer edges of the circlular picture and the sky above the roofs to turn into a blue disk in the middle of the circle (i.e. the very top of the original image converges into a single point in the new).

I have tried using the transform tool but, as you would probably guess, the image doesn't end up very smooth (looks more like a hexagon than a circle)

Does anybody know how to do something like that? Is my explaination clear enough.

Are you talking about something like this?

I love these. The only way I think of you doing this would be to alter the perspective of the bottom of each pic inwards and then stitch them together. Good luck!

Thanks for your responses guys. It's difficult to see if what you suggest is exactly what I want (due to the subject matter in the images) but it certainly looks close. I'll give it a go and get back to you if I have problems
