In this thread, I'll describe how to make some art for your walls.
This isn't audio related whatsoever, but I couldn't find any online forums for laser cutting which covered this, so here we are.

The image that I am blowing up is the cover of the first issue of "Love and Rockets"
I've just been a fan of Jaime Hernandez for decades.

In it's current state, the image can't easily be blown up to put on a wall. Here are the issues:
1) the image is a bitmap and it needs to be a vector to blow it up
2) the image is multicolor and it needs to be monochrome to laser cut it
3) Ideally, I will removed all of the large areas of black, so that the picture can be cut by the laser in less than 24 hours. A laser will happily cut big ol' areas of black, but it takes forever because the laser is a fraction of millimeter wide.
So I have to address issues #1, #2 and #3.
In order to make the picture more usable on the laser, I am taking the JPG that I downloaded off of the Internet, and I am blowing it up using Gigapixel AI.
Gigapixel AI is something like $100 and does a great job of blowing images up to very large sizes.
The pic will probably be about 32 inches wide, so with a DPI resolution of 300, that means I need a pic that's about 9600 pixels wide.

After resizing the image in Gigapixel AI, I load the image into Gimp.
I need to remove all of the colors in the image, so that it can be laser cut.
First, I reduce the number of colors using the "posterize" filter. (Colors -> Posterize)
After reducing the palette, I have to manually eliminate all of the portions with color.
I do this by using the "Select by Color" tool (Shift + C), selecting each color one by one, and then deleting those colors.
Basically taking the image from about sixteen colors to two (black and white.)
Sorry to interrupt, but for Mac or iPad users, Pixelmator’s ML Super Resolution does a great job of upscaling images for much less than $100.
Yep.
And Cupscale is free, and I support the author on his Patreon because Flowframes is fantastic. But if you're willing to buy software to resize images on Windows, I personally prefer Gigapixel to Cupscale.
But, again, there's a lot of ways to resize images using AI.

I've been upscaling movies using AI using a pile of Nvidia cards for about a year now. Great stuff. (It takes about 18 hours to resample each movie.)
