Mood Bag is a piece of interaction design that addresses the struggles of using the litterbags for menstrual litter like pads and tampons (Known as "madamposer" in Danish). These litterbags are often very unhandy to open because of their closed openings tightened by springs - the last thing a woman wants to struggle with when menstruating.

Therefore, Mood Bag incorporates a gesture sensor that easily opens the bag when movement is detected in front of it, and as a bonus, the bag plays a piece of compliment to lighten the mood of the menstruating woman.
