# Simulating the look of curled paper?

Take a look at this image.

This shows a curled paper (dog-ear?) at the bottom right. How do you achieve such an effect (its mere eye-candy, but would be cool) in LaTeX?

Say I want this to show the page number on the "flat" part of the page, in the top right, and just have a curled page like this.

I can think of fancy page, but want to know if there is a package that could do this in LaTeX. Would be useful in producing glossy booklets.

Although this does not look a great deal like the target image, it does reflect the general idea. Moreover, I couldn't find any other question asking for this kind of effect. So I dabbled a bit and fished out some code from the style tcolorbox uses for documentation. I then adapted the marker environment somewhat in an attempt to bring a little life into the curled page. I can't say I'm altogether satisfied, but what I wanted was something which isn't too distracting or too space-hungry, while signalling visually that the content is excerpted from a source. I think the output satisfies those fairly minimal requirements.

I'm posting the code in case this is of any use to anybody else.
