Not to be confused with the Mac OS X widgets thread, this is the Mac OS X screen savers thread (this one's even more useless!).

So, way back in the day, I made some screen savers for the Amiga named "LotsaBlankers". Later on, I ported some of them to Windows, and created some new ones, but I never managed to make a stable and functional enough screen saver under Windows that I'd feel like releasing it. But now that I've got Mac OS X, I've started porting some of this old code over, since making screen savers for OS X is pretty easy and fun. First one I've got running is this one:

http://wakaba.c3.cx/releases/mac/LotsaEscher.zip

It's based on the work presented on this site, http://escherdroste.math.leidenuniv.nl/, and it is liable to BLOW YOUR MIND, MAAAAN. I've been too lazy to figure out how to make a preferences GUI for it yet, so even though the code supports all the possible different transformations of the image (Some listed here: http://escherdroste.math.leidenuniv.nl/index.php?menu=im&sub=escher), you can't actually pick which one you want yet.

There's likely to be more to come. Enjoy!

I really should add a screenshot for this, as nobody wants to download screensavers if they don't know what they look like.

It's not quite the same unless you see it in motion, though.

Also, I finished porting another one:

This one draws snowflakes falling down your screen. Simple enough, but the oh-so-clever part is that it uses a semi-physical model (that I pulled out of my ass) for growing each snowflake, meaning every snowflake is unique (as well they should be!) and also that it uses a quite a bit of processing power. But that's the price you pay for indivduality!

Now features a disgustingly cute options sheet, where you can configure the speed, and the transformation type!

Covertly made a bugfix or two without bumping the version number. If you had any problems with ugly tearing at high speeds, re-download.

Once again, a new screensaver! I love making these things.

This time, it's a fairly realistic simulation of water, distorting your desktop. It eats quite a lot of processing power, especially if you turn up the detail level, so beware.

Big thanks to MrVacBob for help with Altivec optimizations for this one.

Oh yeah: If anyone wants source to try and port these, or just to otherwise play around with, just ask. I'm just too lazy clean it up and package it for each release.

I love the LotsaWater screen saver. When it runs, the background gets duplicated, giving me a tiled look. Have you heard of this before? Is there a way to fix it?
I'm running it on a powermac g5 with tiger.
