The screensaver installs easily, and when activated rotates through two images that slide onto the screen like the opening credits of the game. If GTA: San Andreas Homeboys aren't your thing, there is also a Homegirls screensaver available.

The developer of Dream Aquarium Screensaver calls it a 'next-generation' aquarium screensaver but doesn't explain what they've done to make it so. Whatever it is, the level of realism in terms of graphics, movement and stunningly bright colors is impressive. The swimming actions of the fish are particularly realistic as they nibble bits of food, dart in and out of coral and even chase each other.

The details in Dream Aquarium Screensaver even stretch to moving eyes, gills and mouth and different refractions of light as they hit the water. There aren't many options, although Dream Aquarium Screensaver will at least allow you to display the fishtank in widescreen format and even over multiple monitors if you wish.

Unfortunately, the Dream Aquarium Screensaver trial only features two different species of fish but if you upgrade, you get 16. Note that you'll also be plagued by the odd pop-up window using the demo version.

For pure realism, Dream Aquarium Screensaver deserves full marks but you'd have to upgrade to the full version to do it justice.

Fortunately you can now count on a very original assistant: a little pug who will carefully lick the screen from within the computer. The Licking Dog Screen Clean makes a fun screensaver to gawk at while your PC is idle, although the screen may not end up as clean as you expect!

Licking Dog Screen Clean features a high image quality, complemented by dog sounds. It would have been great though to have more dogs to choose from or maybe another breed – but pugs are still really cute.

If this little pug isn't to your liking, why not check out some other animal screensavers?

Licking Dog Screen Clean is an adorable. Pity it doesn't include more breeds.

Transformers fans have probably already played the PC game demo, and have possibly already seen the movie.

If that's the case but you're still trying to get your sci-fi fix, consider adding this sleek-looking screen saver to your Transformers repertoire. The colors are superb, with a metallic blue and red robot eye at center, overlooking the horizon of planet Earth, and a darker black void bordering the image.

It would've been nice if there had been some sort of animation included in this screensaver. The lack of it might be disappointing to some users although it's hard to complain about the graphic's crisp details.

Transformers is a nice looking wallpaper that commemorates the movie of the same name.

Photo Mishmash Screensaver gives you exactly the same kind of effects but in a screensaver - so now you can watch your warped face swirl around your screen when your computer wants a rest. Photo Mishmash allows you to use your JPEG & PNG photos, web graphics or clipart, and then proceeds to squeeze, stretch and swirl them until they are no longer recognizable.

What you see can be both funny and horrifying as your face becomes distorted out of all proportion like some Star Wars character gone wrong. Photo Mishmash continually feeds images into itself so that no two screensavers are ever the same. You'll have a lot of fun just sitting back and watching it go to work on your face. Photo Mishmash Screensaver is only suitable for high resolution monitors though because it only displays images in Hi/True Color mode (16/24 bit color) and not in 256 color mode.

Photo Mishmash Screensaver is great fun and will provide hours of entertainment as well as of course, protect your screen.

The GTA IV Screensaver includes snapshots from game footage and displays them on your computer as a photo slideshow. But that's not all: the screensaver will automatically connect to the GTA IV official website and download more screenshots as they become available to add them to the screensaver.

On the downside, I missed some basic configuration settings, like being able to set the time period or even choosing between different transition effects.

In all, the official GTA IV Screensaver lets you take a sneak peek at one of the most awaited games of this year and keeps you updated with new screenshots.
