Cool... Watching the seconds tick by, with the background moving, is almost hypnotic... I watched it for almost a minute and it didn't effect me effect me effect me

Thanks guys, we are continuing experiments and learning to get some control over the stuff we call plasma. :)

And the results of study are in:

A new updated Plasmatic with (255^3) ^ 2 more color options! Plus color palette creation demystified (I hope) and code more completely documented with comments. This demo contrasts the Traditional high contrast Black and White Plasma palette with the newly updated full color range options for color palette creation for plasma.

I mentioned it was meant for SmallBASIC 64 bit, perhaps I should have emphasized it:

Plasmatic stuff meant for SmallBASIC 64 BIT  :))

I look forward to day someone else posts code for SmallBASIC here at this forum.

Anybody know the Moody Blues song, Watching and Waiting?

Wait a moment ...dude
I tried both ...32bit and 64 bit versions on both
win7 . 32/64 bit
win10 32/64 systems
yes I have all of them
and still work slowly...soo please without patronizing .. ;)

Well that's funny, I checked out the code posted running it in SmallBASIC version 12.17 64 bit and it was not recognizing key presses??? The code runs slowish but not bad for interpreter.

So I check it out in version 12.13, yep! works fine with key presses.

So I check it out in new editor, there it runs slow as the dickens but key presses are recognized.

So pick your poison ;-))

Oh snap it works fine in the linux version :)  I will fix and push another update.
I will see what can be done to make the FLTK version a bit faster.
