NOVA was written with the intent of creating a stable, application based screen saver. Most of the screen savers available do a lot of system trap patching via extensions, which introduce a factor of uncertainty in your system. NOVA does not patch any OS routines, but instead is completely application driven -- when it is appropriate (based on user settings), NOVA will launch it's "Saverlet" applications that will do the screen saving. NOVA provides three main services to the user: (1) eliminates the potential for phosphor screen burn-in, (2) provides security for your system via password entry, and (3) provides entertainment for yourself and those who work around you. One last boastful note: NOVA is one of the only screen saver applications that can utilize multiple monitor setups-- and when we say "utilize", we mean that drawing occurs on ALL monitors, not just the menubar screen. Take that After Dark!
Full Specifications
What's new in version 4.1
Any application can now be a NOVA 'saverlet'. Simply drop any application you want to be launched when the screensaver is supposed to kick in into the 'NOVA Saverlets �?�¸' folder, and it will launch it when appropriate if selected as the active module. However, these pseudo-saverlets will not conform to true NOVA saverlet specifications, and as such will not provide security and other saverlet-specific features
Plugged security hole -- we now disable the hot-key application switching mechanism (if it is active) when a module launchers so you cannot switch out of the screensaver
Fixed interoperability with other applications such as Drop Drawers - they will now hide their windows when a module is launched
If modules are somehow put in the background (by Sherlock's disk indexing, for example), we now bring them to the front again
