The Mystical Code When our group started this design project, the final interaction effect is actually not as expected as its imagined to be stunning. However, due to the limitation of our programming ability, we are not able to write a perfect program, but in general, it is a playful interaction device. Its simple and three-dimensional structure is very easy to attract audiences’ attention, the color transforming process of the light pushed the pleasure interactive experience feeling to the climax. But this interaction process is transient. Just in a few seconds, audiences can explore the correct interaction way by themselves, and then complete the whole interaction experience within the next 10 seconds. This is just a quick and short-fresh interactive process. As for whether the audience can reflect something or learn something new within few seconds, we have no ideas about this… but in just a few seconds, people got a sense of achievement by controlling device and operating device, their facial expression is happy and joyful, this is enough
