Linda,Everyone seems to miss the point that your asking about the POP-UP flash, the one that comes for free on the 40D... As far as trying to diffuse that flash I suppose anything is better than nothing... there was a type of DIY attachment I saw somewhere online where you could direct it up to the ceiling... that would be better... As far as the comments about the Fong diffuser for Canon Speedlites, yes it should be avoided for most applications! Ah ha! Someone actually read what I was asking lol.
Re the DIY attachment, thanks for the suggestion, but I was after something small just to clip on. You see I have an external flash - the 580EX and I also have 2 diffusers, Lumiquest SoftBox and also the little Stofen OmniBounce, so am not interested in any Gary Fong stuff, it was the simplicity, size and quickness of attaching it that appealed to me in the first place.
Thanks very much for your input 
Linda

A pecpad rubber banded over the pop up flash does a great job diffusing and softening the light. If you leave it a bit poofy it diffuses more.
Ooh now that sounds interesting - I have some of those so might give that a try - thanks for that 
bieber: oh yes, I had forgotten about the ping pong ball suggestion, thanks for reminding me of that one, so thats another option.
Thanks everyone for taking the time to respond to my query - let me explain:
Ok, I will just clarify for all of you that were kind enough to respond, I do have an external flash with 2 diffusers, a Lumiquest Softbox and the little Stofen Onmibounce, so I am not interested in any other Gary Fong equipment at all. As I mentioned above, it was the size and simplicity of that particular diffuser for the pop up that appealed to me.
I use flash primarily for macro shots and just the occasional fill-flash for other stuff, hence my wanting something quick and small for days when I am out doing wildlife photography rather than macro (mostly in my garden).
I like the idea of the pec pad and also the ping pong ball which I had forgotten about. I had even tried cutting the handle of a plastic milk bottle as I had remembered that one from ages ago but it didnt work for me (I probably cut it wrong lol).
I get the drift though, in general the opinion is Gary Fong stuff is to be avoided
- thats fine by me, so thanks for the warning lol.
Thanks all again.
Linda
