Jodan Merrick writing on his blog found via Supercomputer:
Instead of framing screenshots using just these images, I wanted to create mockups using different product images that are more distinctive and, in some cases, three-dimensional. The result is Mocktail, a shortcut that creates framed iOS screenshots using various device images I’ve sourced from Apple’s website (e.g., product landing pages or the online store).
This is some of the most extensive and beautiful work I have ever seen in a Shortcut. Jordan has created something incredible and I plan on using it every chance I get.
Just look at these screenshots I used with this Shortcut
