I’m all for brain teasing toys but I never had a knack for them. I blame my parents. Don’t make the same mistake and get your kids an OBLO - a 3D didactic puzzle sure to gift them with powers in spacial geometry. Designer Marko Pavlovic believes it engages children on an emotional level and encourages growth thru the development of investigative and problem solving skills. Intrigued?
OBLO is a 3D puzzle made of differently sized, shaped and colored spherical elements that need to be twisted against the central axis in order to disassemble and fully reassemble the toy. It consists of an outer round layer (the container), a lid and 10 removable pieces. OBLO is colored with three primary colors and one secondary color to appeal to its audience, children between the ages of two and five. Color is also used to emphasize the different layers lodged inside the toy.
In order to successfully progress from one level to the next, the child needs to find the correct orientation for each piece that will enable their smooth passage through the fixed opening in the outer layer. Using this method, the spherical elements work as part of a bigger unity. The link that connects all the pieces is their shape, which matches the opening in the outer layer.
The degree of difficulty can be modified for different age groups. To make OBLO easier, the open space in the outer layer can be enlarged. On the contrary, the difficulty level can be increased by using a larger variety of shape types. Also, the number of layers can be increased by reducing the thickness of each layer or by modifying of the diameter of the outer layer itself. Colors can also influence the degree of difficulty.
By playing with OBLO, children are encouraged to discover new possibilities, new ways of disassembling and reassembling the pieces. Through interaction, the toy’s didactic features are emphasized in an imperceptible way to the child. However, for parents, the secondary target audience, this will be an important marketable element.

让人抓狂的益智魔方【奇客】
我一直想要益智玩具，但我却不擅长玩它们。我想这得怪我的父母。别再犯和他们相同的错误，给你的孩子卖个OBLO——3D立体魔方，培养孩子的空间想象力吧。设计者Marko Paviovic相信它能提高孩子的情商，培养孩子思考和解决问题的能力。怎么样，对它好奇吗？
OBLO是一个由不同尺寸、形状和颜色的球体元件组成的，你必须绕着中心轴扭动这些元件，把玩具分解然后完全重组。玩具包括一个外层（容器），一个盖子和十片可移动的元件。OBLO涂上了三基色(红、黄、绿)和一种合成色（蓝色）来吸引2~5岁的小孩。不同的颜色还能强调不同的层在玩具内部的位置。
为了顺利地进入下一层，孩子需要为每片元件找到正确的方向，让它们顺利穿过外层固定的出口。用这种方法，所有的球形元件成为一个更大的整体的一部分。把所有元件联系的关键是它们外层出口相匹配的形状。
玩具的难度可以根据孩子的年龄层进行调整。为了降低难度，OBLO外层的开口还可以扩大。相反的，也可以增加不同形状的元件来提高难度。同样的，还可以通过减少层的厚度来增加层的数量，或者是调整外层的直径来增加难度。颜色同样也会影响到难度。
通过玩OBLO，孩子能发现新的可能性，新的方法来分解和组合这些元件。通过互动，孩子们可以在不知不觉中受到教育。然而，对第二受众——家长来说，这是个重要的卖点。
