I like the idea. I really do. I think it's touching that you want to preserve these snippets of your grandfather's memory. That enjoyment is quickly overshadowed by this page demonstrating everything I hate about the current "responsive" "disruptive" "Valley" "mobile" fetish:
* It shouldn't take 30 seconds or more to load some pictures and text in an HTML document. Additionally, I shouldn't be sitting there the entire damn time watching some little animation spin around while it struggles to load.
* I really don't need an ugly 900pt font in order to read your homepage. While your grandpa might have poor vision that warrants that, I don't. I'd reckon the vast majority of your site's viewers would be fine with your run-of-the-mill 12pt font; people with visual impairment typically have other accessibility tools at their disposal.
* I really shouldn't have to scroll down a whole page for every single goddamn sentence on the homepage.
* The fancy "hover over this part to bring up a menu" is buggy because it overlaps with the "hover over this part to bring up an arrow" crap.
