I spotted Jim running the Fracture screen saver on his MacBook the other day. Beautiful - worth £5 of anyone's money.

"As you can rely on with Stick Software products, it has a suitably overengineered configuration panel that lets you control many details of its operation." Outstanding.

It joins my ever growing collection. I love Skyrocket and Hyperspace, (I've mentioned Skyrocket before) and Euphoria, Solar Winds, Flux & Fireflies. (These also offer config screens with all the frobbing and tweaking opportunities that you could ever want.)

For traditions' sake I also have Red Pill and PongSaver. Oh yes, and a couple of Life savers that I can't seem to find links for any more.

That's a lot of screen savers. I don't want to be fiddling with them all too much. Fun screen savers are enough of a productivity sink as it is - I don't want to be changing my mind as to what to run all the time. And I don't want to use the Macs built-in screen saver randomiser, 'cos it's an all or nothing thing. Though I do like the iTunes Artwork & RSS Visualiser savers, there are a lot of the built in savers that I don't want to see.

Luckily, there's RandomExtra. Like the built in randomiser, it picks a screen saver at random, but it also allows you to select which of your installed savers you want it to pick from. What's more, you can weight the savers - so I can choose to see Fracture twice as often as PongSaver, for example.

Naturally, I just spend ages fiddling with RandomExtra, instead. Sigh.
