This effect was generated in Filter Forge, a Photoshop plugin that allows you to create your own filters.
If you want your image to break apart in a weird way then this is the filter for you. You can create nutty looking cracks that totally defy the laws of cracking.
This filter is a spin-off from 'Abstract thornbush'. Thanks to StevieJ for pointing me to Uberzevs unsubmitted cracking filter.
