Morph is a stationary that can be folded to meet the user's needs. Since in nowadays the life we have demands us to travel and often change our work environment, it would be good to have a stationary that can take all the shapes that can be needed and than, change into a flat form that cant fit into a pencil case. You can take your personal space with you without volume or weight problems.
