I remember using page transitions as a teenager to emulate PowerPoint in a programmable info-screen thing for the school library. Baby's first PHP. Lots of copy-and-paste cos I didn't really understand the fuss about writing functions. Good times, RIP.
Oh yeah, Powerpoint Jeopardy! I remembered we did that in high school science class once. Totally forgot about powerpoint being able to link buttons to different slides but in that case I do think it was a lot of copy and pasting.
