Cooliris which is the second featured add-on is one
that I liked.
It might not be good for those of you with 'dial-up'.
I have now had a look at the information now and I feel it may have the reverse effect as it would be trying to load tens, hundreds, thousands of 'small' images into the 3D wall and that would just swamp what little bandwidth available.
I think when they talk about speeding up searches on images, youtube clips, etc. they mean making it quicker to find what you actually want not quicker loading, etc.
The idea of the 3D wall is you see the small image so you can effectively ignore those that don't really match what you are looking for, effectively filtering out the dross, so you can o to those that are closer to what you want.
