Toonification, just one of the many possibilities.

As Jon got up, he realized why it was that he tripped when he got out of the light. He had heels on his feet. But they weren't just normal heels; Jon could tell they were toon ones by the smooth, paint-like texture and outline. As Jon watched, the change crept along his legs, his legs becoming shapely and also outlined and painted. His jeans and shirt became a very sexy red dress, and his arms now ended in - also toon - purple gloves. Jon felt his hips, waist, ass and tummy all become sexy and feminine, and his chest became a huge pair of toon breasts. His neck became sexy, his voice becoming Jessica's breathy one as he moaned. His face changed, and finally his hair became a solid toon mane, which insisted on falling on one of his now-toon eyes. Jon, now Jessica, could now tell that she had a few toon powers and would not die at all unless hit by the "dip" from the movie. She knew anything she put on would become her sexy dress. All this knowledge came from the change, much like that executive had learned how to hover as a faerie. And, despite all this, Jon could only realize one thing in the middle of all the changes: If a simple ray can do this, and a slight oversight can make it possible for sunlight to cross through, then most people would almost certainly change very soon...
