The OldSkool DemoMaker creates demos like cracktros on the good old Amiga. Here a list what you can do with it: Horizontal and sinus scrolling text, bouncing copperbars, starfield in three modes, colorfull plasma effects, logo with old stylish deforming effect  or as gif anim, 3d ball, dot & vector object view with rotation, replays music in different sound formats eg. SID and V2M, free use of display (window or fullscreen), export optimized standalone executables (no files needed), compressing executables will shrink size upto 90%, able to pack medias to use real large files. A lot of bitmap fonts and tracker modules included. O.S.D.M could be an ideal tool to put your own demos within archives to introduce yourself.
