│ This is a graphics program which will transform your PC into your own │
│ "Laserium", displaying many fascinating patterns. The patterns │
│ displayed are complex lissajous's figures ( - Pretty patterns to most │
│ people). │
│ │
│ It will run on any IBM PC or compatible with a suitable graphics │
│ adaptor and requires DOS 2.2 or higher. │
│ │
│ The program will identify the video subsystem in your PC, select the │
│ most suitable one and then display a pattern. If LJ.COM can't find a │
│ suitable graphics mode (This problem is most likely to occur with IBM │
│ compatible machines) but your PC is capable of using one of the │
│ following graphics modes :- CGA, HGC, EGA, MCGA, VGA; then you can │
│ force LJ.COM to use a particular video by entering LJ /x - where x is │
│ the first letter of the video mode you want to use (C,H,E,M or V). │
│ │
│ NOTE - If your PC is NOT capable of using the selected mode it will │
│ probably crash - requiring you to reboot your PC. │
│ NOTE - Even if LJ does appear to run, it is worth exiting from the │
│ PC menu system and starting it up manually with the required │
│ parameter. This may give better results. │
│ │
│ When you run the program one of 16 patterns will be randomly selected │
│ and displayed on the screen, with a control panel beside it. The │
│ controls are simple but require a little getting used to. Online help │
│ is available. │
│ │
│ ┌────────────────────────────────────────────────┐ │
│ │ │ │
│ │ The secret of good patterns is to get the │ │
│ │ harmonics multiples of each other; │ │
│ │ (1:2:2:4:2:2:4:1) - Have fun; EXPERIMENT │ │
│ │ │ │
│ └────────────────────────────────────────────────┘ │
│ │
│ You can also select which of the 16 patterns is initially displayed by │
│ entering LJ /nn - where nn is a number between 1 and 16. It is │
│ possible to force the video mode and select a pattern at the same │
│ time. ( e.g. LJ /c /12 ) │
│ │
│ If you are interested in these patterns; the full version includes the │
│ following EXTRA features :- │
│ │
│ Automatic mode - Where the pattern selected will gently change - │
│ never repeating itself ! │
│ │
│ Screen Printing - For hard copies of your best patterns. │
│ │
│ * FULL COLOUR * - For those of you lucky enough to have EGA or VGA │
│ adapters and a colour monitor. 16 colours of the │
│ rainbow displayed at top resolution. │
│ │
│ Colour Rotate - Where each colour independently changes through the │
│ colours of the rainbow. Has to be seen to be │
│ appreciated !! │
