How to surprise lamers with demos?
Open a DOS like window and run your Windows demo from it,
open a linux X window and launch a windows demo from it,
and vice versa under X,
open a Mac OS X windows under windows and run your Windows demo inside,
open a windows window under Mac and run your Mac demo inside it,
open a browser like window and run your windows demo inside it,
...
You've understand the principle :
open an alien OS window and run your demo inside.
Thank U Mr Hyde of Andromeda / Amiga for the idea.
We can enlarge the concept:
run a windows demo on a C64 (well, not possible),
but run a c64 looking like demo on Windows,
run a ST looking like demo under Amiga,
run an Amiga like demo under Windows, Mac OS, Linux...
Run old consoles stuff demos under windows, ...
Special effects:
Fade, distort, lazerise, ... alter the Windows desktop then run the demo: you take a snapshot of the system desktop then copy it to a directX fullscreen window and do whatever you like, at the end you do the reverse, to go back to windows desktop.
With the copy buffer, make the mouse pointer 10 times bigger and move it from left hand corner of the desktop, then select everything and put it to the trashcan :), then end the demo. Hopefully everything is there.
