If during your life in front of the PC you have installed a lot of screensavers and are tired of them all, why not try Flash2X Screensaver Builder. It lets you create your own screensavers.
The screensaver content in Flash2X Screensaver Builder is obtained from Flash animations or videos, so any SWF or FLV file will do. Once generated, you can convert it to a runnable, so you can then distribute it to all your contacts.
To place your signature on each of the screensavers you create, Flash2X Screensaver Builder lets you add your own logo. You can also apply a password, so that only you know the key to running it.
