Hello guys!
I really need some patch to light paiting , equal to this experiment here:
Please help me!!

And I need a million dollars! please help me...

Don't expect someone to provide a finished patch of this level. You'll need to work your way through it. Otherwise buy some software that does what you want.
I'd start with [pix_delay] and [pix_buffer], though I'm not a visuals guy so I don't really know how to achieve this. But it does look like some infinite loop of delayed frames being written back to the frame buffer.

@alexandros Hello Alexandros...... you need to post your bank details........ You never know!

We don't have a machine that can make a perfect replica of a million dollars for zero marginal cost. We do have that for Pd patches. Plus we do have evidence such a patch exists on at least one machine in the world.

So if you have it, or one like it, make the bits available for the OP to copy.

@andrezzamfs If you speak French you will find out how it can be done in the link below.
If you have experience using "max" (or more accurately if you have "Max") then you can build the patch in the photo, but otherwise if you read the text you will be able to understand how to build a "light painting" patch in Pd.
There are other patches around for making "synchronised sound to picture" patches.......or you could adapt their ideas and make a better? one.......... which you could then link to your light painting patch.........

@jancsika what I mean by "I need a million dollars" is that according to netiquette in forums, saying "I need bla bla... please help!" is not playing nice. If we all asked for what we need this way, there would be no real community or real knowledge in programming.
Providing a patch to someone because of a uni class or whatever else is not the point of this forum. What's your take on this?
