I use the Everchanging in my phone.
The "Everchanging" theme consists 6 thm's (2 of them are the same thm with different name), 1 standby swf and 1 menu swf. 5 of the thm's are placed together with the flash menu inside tpa/preset/system/desktop/flash and the other 1 thm are placed in the Theme folder where we used to saved our theme collection and the standby swf are placed in tpa/preset/system/standby/flash. Those 5 thm's are controled to change automaticly by the standby swf to match the colour of the standby swf
Itself. So when the standby goes greenies (usually in daytime) it will send command to activate the green thm and so on.
Sorry for my english...
