As mentioned in my Pink Forst deviation below, this is the action I was working on. Made in PS 7, suitable for all other versions of Photoshop except Elements.
Works/looks best on pictures with a lot of green and neutral tones. Try upping the saturation of those or making the picture a little more green (e.g. in Image > Adjustments... > Variations...) before playing the action. Also I have made it so the layers won't be merged at the end of the action. Try hiding some of the layers (click on the little eye icon in your layers pallette) to come up other results! Download, un-zip, save the .atn-file to somewhere you would easily find it, open up Photoshop, open your actions panel and load it
