Welcome to the world of Ogless.
With unrivalled flexibility and variability Ogless is a screen saver you won't get tired of.
Ogless packs a lot of power into such a humble thing as a screen saver. It provides facilities to let you interact with the screen saver while it is running and download new effects from our web site. Compare this with some of the 'free' savers that come with Windows that repeat themselves contiuously and have no configuration options at all.

People who remember computers from the 1970s were all too used to finding a monitor with an image ‘burnt into’ the screen. If the same screen image is shown for a long time the screen phosphor that radiates the light is damaged and whatever has been displayed for a long time shows through any other information displayed - it gets burnt in. The earliest and still most effective screen savers just ‘blank’ the screen or automatically turn off the monitor and so prevent screen damage.
However, the knowledge that the computer is normally idle when a screen saver is run haunted programmers. Why not use the ‘idle’ time to display something more interesting than just a blank screen? If an image moves around the screen it will not get burnt into one place. The other less interesting reason for screen savers is security - if someone leaves their desk for a few minutes they may not want the screen contents displayed for all and sundry to see.
Ogless is designed for high specification PCs running either Windows XP® or Windows Vista®.
Some of the screen savers use up a high proportion of available processor power and memory space to achieve the interesting screen effects.
If your PC is carrying out useful work when it is left unattended run only some of the less demanding saver effects or run savers at lower speed settings to reduce the effect of running them. A special 'low load' scheme is provided that can be used to reduce processor load.
Many computers now support drawing objects in 3-D. Ogless offers a number of effects that can make use of these facilities - if they are available. Most Vista® PCs will support these exciting possibilities. To use them you will need to have a compatible version of Microsoft®'s DirectX®. Ogless will guide you through checking and installing this when it is installed.
Graphics capabilities have come a long way from the first PC that supported two colors (black and green !) or at most four. Unfortunately Windows was devised when graphics cards that only had a very small amount of memory. Early versions only supported 256 colours at a 320 by 200 resolution - because of the 64K video memory limit.
Some of the savers manipulate the screen image directly and need to know how the video memory is organised and may not work on non standard numbers of colours. The colours supported are : 256 (8 bit), 32,768 (15 bit), 65,536 (16 bit), 16,777,216 (24 bit) and 32bit. You can check how many colours are available on your PC by using the ‘Settings’ tab on the Screen properties sheet.
The most popular screen setting with Windows is 1024 by 768 pixels. Ogle was devised with this screen resolution in mind and so you may have problems with very small or large settings. 860 by 480 is the smallest suitable setting, 1280 by 1024 the largest.
