Trapcode Echospace is a new plug-in for Adobe After Effects 6.5. It is used to duplicate, manage and animate layers in a convenient manner. It works similair to an echo effect, but instead of creating 2D echoes, it creates new instances of a layer in 3D space - hence the name Echospace.
Trapcode Echospace can be applied to footage, text, solids or even nested compositions. It features a built-in animation delay to create time-rippling effects. It can also add randomness to the positions of layers to spread them out randomly in 3D space.
The price is USD 49. More info here:
