It depends on what you mean by that. I spoke to WattaWright a bit in the chat room, he had assumed you're wondering about the code for falling cherry blossoms?
I seem to recall a thread on Guild about it also. But yeah, if you're main intention is to have them actually fall on the ground or spin (like I'd done in the MBAA stage collabo with XTRM) BG CTRLS would be the best way, unless you were to sprite every single motion the sprite makes. Which would be a bit excessive.
However, If you just want them to fall, that could be done easily with tileing or animation.
@ WattaWright. I don't use Photoshop, so I don't know if i'm much help while saying this. However, when I use GIMP and I run into a situation like that I go to layer - Transperacy - Threshold Alpha (Left at 127). On the cut/sprite I've placed on the Green or Pink BG. Maybe you could find the equivalent to the threshold alpha in photoshop? If you can find that it will stop the sprite/cut from blending into the BG color and you can merge and index with no issue.
