You can either purchase one that is specifically made for built-in flashes or you can make your own from materials you can find around the house.
The diffuser shown in this instructable is great for diffusing and directing the flash to a specific area. I mainly use it pointed upwards so that it reflects the light off the (white) ceiling and onto the subject. You can aim it in any direction by angling it or making the hole in a different part of the cup.

PS: In that last foto, isnt that Canon EF 50mm f1.8?? Ive just bought one in ebay right now :D Do you like it ?
And yes, that is the Canon EF 50mm f/1.8 II. It's a great lens that never leaves my camera bag. It's small, light, sharp, and fast. I used it exclusively for 6 months before I bought a wider lens. You won't be disappointed with it. And if you reverse mount it you'll have yourself a decent macro lens.
But with the difuser you invented i should increase the flash exposition or not?
When using flash without the diffuser, the light is going directly at your subject so you don't usually need high flash exposure compensation. But using the diffuser makes things a bit more dependent on your environment. Since this illuminates your subject by bouncing light off the ceiling and walls it would really depend on the colour of the walls & ceiling and the height of the ceiling.
If you're shooting a high or dark ceiling then you'll need more flash exposure compensation. If you're shooting with a light, low ceiling then the you won't need to increase the value by much, if at all.
The best way would be to experiment. There are many configurations for lighting so the best way to really learn which is best for a situation is to try it out.
