DoomPDF #
The highly anticipated sequel to PDFTris. It’s surprisingly responsive for how limiting PDFs are, but it makes sense given that most of the logic is just JavaScript.

Cool demo of the concerning program execution that is built into PDFs. I initially assumed that PostScript was used to add logic, but it apparently instead uses JavaScript, which I didn’t know was able to be embedded into PDFs. Note that it doesn’t seem to work in Preview.app, but it does work in the builtin PDF viewers in Chrome and Firefox.
