Mafro.ca was a site started in 2014 as a means of developing any semblance of web development skills.
I have moved onto greener pastures and bigger projects since then.
The largest success was a page for a countdown of GTAV on PC from september 2014 to april 2015. It reached over 460,000 hits, with over 160,000 hits on the final day alone.
Below are some pages that still work today which you can access.
If you can't find the page you remember, a lot of the web has changed since 2014, so it probably used embedded media that no longer works today and thus has been removed.
Some secret pages exist.
