InstantStorm is a Windows freeware tool for creating Flash based screensavers with many advanced features. All you have to do is to choose a SWF file, set screensaver parameters and compile an executable installer. All 32-bit and 64-bit versions of Microsoft Windows are fully supported, including Windows 95 and Windows Vista. And the best of all—there are no nag screens or other annoying stuff.
