As the topic of this design project is " Playful " which literally means " somewhat naughty " and " lively ", I chose a lively animal, the money, as the theme of my product. In my design, I used a lot of bright colours to make it look energetic.

The materials I used are plastic bottles and lids. Together with some abstract ideas and the characteristics of a monkey, I managed to visualize the image of being playful.
