I’ve just been developing some ideas for prints using FPDF to dynamically create the PDF’s. They consist of a grid of objects in these cases, letters and shapes, where each element can have alternate properties applied to them. The text based is great and things like poems would easily be incorporated, and give it meaning. All prints ratio/sizes can also be altered simply, so any size can be output.
Above: A string or sentence with a message displayed in the middle, in this case fruits.
The same example with different colours and grid size.
