Did you actually read Dr. Lava's response:
LaserBoy (ilda editing and wav output)
LaserWave (abstract generator)
HE-Laserscan (laser show software, music synchronization)
LFI player (live spontaneous shows)
OLA (laser art creation)
Monkeytools (laser art creation)
Heathcliff (laser art creation)
Sergy's tools (see on this forum)
and more...
More than 1 of those you can use to draw/make ILD files. Let me reiterate which exact ones those are:
LaserBoy (Google knows where this is)
OLA (Converts Inkscape V0.44 or earlier? to ILD files)
MokeyTools (on the FTP site in the old ILDA swap folder)
Heathcliff
Sergy has a couple of tools that (Bitmap Tracer and an drawing program) both which work well and are nice. All of which can be found in the Programming section of this forum...
Now if you need help finding those ... search is your friend ... and then if you still can't find them just ask where are they and I am sure someone will pop up a link or 2.
