If you have an IPhone/IPod and interested in some studio photography and lighting, this application might be very useful.
As for the demostration of this little app, It looks very very impressive. For only 3.5& you can get a mobile studio light simulator, this is simply amazing.
So what it does?
The app allows for setups to be quickly laid out and added to the library.
A video of the app can be seen on the SLR homepage (just follow the support/homepage link).
Have fun and suggestions/ feature requests are most welcome :).
(From iTune store).
So you could check this one for your own.
