I used HTML5 just because the original version was made with Flash back in 2006 (<a href="http:&#x2F;&#x2F;pakastin.fi&#x2F;cards_2006" rel="nofollow">http:&#x2F;&#x2F;pakastin.fi&#x2F;cards_2006</a>). Then I made a Angular.js version, which is lost, but was featured on Chrome Experiments. This is actually HTML5 Deck of Cards 2 :)
