My old homepage from nearly 10 years ago was a page that looked like it was straight out of the late '90s but was entirely valid HTML5 and CSS 3. That included an applet-like rippling water reflection effect beneath a photo of my city at the time, MIDI audio, JavaScript emulating the blink tag, and right-click "image save protection."

It was a total blast to make and people loved it, but being in the tech industry it kind of gave the wrong impression to hiring managers, so I swapped it for a much more boring page.
