Fan art hobbyists have found a new way of reimagining their favourite characters, thanks to the magic of heat-activated erasable ink.

Pens such as those from Pilot's popular Frixion line offer users the ability to rub out their mistakes. An acid in the ink is activated by the heat produced from the friction of rubbing, which then dissolves the visible marks from the page.

Naturally, people have figured out some naughty interpretations -- such as erasing girls' clothes with hairdryers held over the drawings.

Maybe in the future we might see publishers printing art with erasable ink, so readers can transform the drawings with the humble hairdryer.
