Aaron Tang‘s Anemone Clock awakens you by means of sound, light, movement, and interaction. When the alarm goes off, it rumbles intensely, making it harder to find the off switch. Due to the rumbling, the clock also bounces away from your bed table, so you have to get out of bed and chase it like a pet around the room if you want to silence it.

Other challenging alarm clocks: : the one that hides, the one that drags you out of bed, the teddy bear-activated one.
