Sensuals doing some work here though - that flame is sensual, but also gives immediate feedback over temperature/spread. You can lift your pan up and down to control heat over a gradient that radiates above over a larger distance. That lifting and moving of the pan alongside adjusting the flame and seeing it change immediately combines to give you a lot of control. So sensual, yes. A lot more intuitive and powerful, too.

Metal slats are also nicer to hit your a pan against than flat glass for a variety of useful/sensual reasons.
