Filter Forge is a plugin for Photoshop that lets you build your own filters. It’s visual and node-based. You can download almost 6,000 filters that the community have developed, and if you submit your own, even earn a free license. The examples are actually pretty good (as opposed to endless variations on bevel and emboss).
Filter Forge. I think we need something like this for After Effects …
