Interaction techniques for flexible displays

A reusable portable interactive apparatus, comprising:

• a container portion with a display comprising a flexible display technology and a display surface visible on an outer surface of the container portion;
• a base portion;
• a computing device electrically connected to the flexible display technology, comprising one or more of battery, power connector, network connector, audiovisual connector, central processing unit, wireless network transceiver, graphics circuit board, RAM memory, firmware ROM, flash memory, and hard disk drive;
• at least one liquid chemical sensor in communication with an inside surface of the container portion that senses a chemical characteristic of contents of the container portion, and outputs a chemical sensor signal to the computing device;
• at least one motion-sensing device that senses motion of the apparatus and outputs a motion sensor signal to the computing device;
• wherein the computing device produces an output based on at least one of the chemical sensor signal and the motion sensor signal;
• and
• wherein the computing device output comprises one or more of a visible change in the flexible display, a change in a wireless network transceiver signal, and an outputting or receiving of a wireless network transceiver signal.
