but how do you get that "fireworks" effect when you close windows
First log in to "E17 - Ecomorph" session (you need 3D acceleration enabled). After this, type in the command launcher on in a terminal
ecsm
Enable the "Animation" plugin, open it, go to "Close Animation" tab, click on the "Add" button.
In the dialog Window choose "Burn" as effect, 350 ms as Duration, and the string below as Window match:
(type=Normal | Dialog | ModalDialog | Utility | Unknown) & !(name=gnome-screensaver)
Click OK and put the animation you made in first place.
how do you get the flames across the bottom of the screen?
Go to E Menu -> Settings -> Modules. In the left side of the window choose the "Flames" module and load it. This effect is cpu-intensive, so if your computer is not powerful it may slow down.
