ive tried them both, and i like deepend better. im not seeing a difference, but some people are saying that 3dboard moves the icons, and deepend moves the wallpaper. but from what ive seen, they perform the exact same way. the only difference is that 3dboard is non-ip4 compatible. also, something someone mentioned, if youre not seeing the 3d'ness that was in the video put out by the dev... look at your iphone screen with one eye closed.
