Play is a significant part of child development. It allows kids to use their creativity while developing their imagination, dexterity, physical, cognitive, and emotional strength. The project “Busy rock” was created in a collaboration with Stokke®, a Norwegian distributor of children’s premium equipment and furniture. The brand is currently working on a new line of the products which are fun to play with and most importantly help children to learn and develop. The purpose of that diploma project was to make first steps into creating a new product for Stokke®, that will be fun, unique, and challenging at the same time. “Busy rock” turned out as a fantastic way to explore, experiment, reflect and moreover, I had a great fun by testing my concept with the little users! “Busy rock” is a combination of games that develop variety of skills but also provides an opportunity for an active play. Child can flip and rotate the shape, draw on a chalk board, sit on the top surface and drag “Busy rock” around using the handle. The material for the installation plates and profiles is plywood covered with beech veneer. The connections - joins between profiles and plates are produced from colored PS6 plastic. There is also a stor-age function, a child can keep the geometrical figures inside and even put his favorite small toys through the hole which is covered in soft rubber and felt. On the other plates, I put the flip game with figures which are different colors to develop memory and concentration, on the other plate, it is a fun game with magnet clocks that teach children to count. To make my project more sustainable, I have been talking with Stokke about an exchange solution. The idea is that parent buys a base structure with a set of plates for age 2-3, and then after a year when the child grows older and gets bored with old games, parent can send them back to Stokke for renovation or recycle and get new set of games with a dis-count. Also, that is a great opportunity to make “Busy rock” more personal oriented since each parent can adapt my concept for the interest and needs of their children.
