This reminds me of all the unholy things I’ve seen done with excel over the years.

One guy I worked with at a big corp IT shop had broken PowerPoint and the IT guys couldn’t fix it (turned out to be a profile corruption issue). So he did his presentation in excel with and wrote something that captured a mouse click and used it to activate the next sheet in the workbook. I was vaguely impressed as he wasn’t a programmer by any means.
