When someone gives me help I feel that I have to pass it to somebody else.
The cubes make me perceive the help in a physical way, which encourages me to give them away
It was useful, approaching others was easier.
The received help is materialized using the cubes. It becomes clearer how much help you have received
Sharing knowledge makes me excited and motivated about my work.
If somebody else looks at your project you get different insides. It's very useful.
