Mis Buggie (limited edition of 500 copies) is the result of of a collaborative design project between Spain’s AIJU (Technological Institute of the Toy), industrial designer Jorge Vega and illustrator Sea Hernandez.
Their website (in Spanish, here’s an English translation if necessary) has a walkthrough of the toy design & development process–a great tool to teach your kids how things are made!
NOTE: Unfortunately, the website is no longer active.
