Xtreme55 is an event-organizer company head-quartering in Jakarta, Indonesia. The sharp-line dominated 'X' shape of the logo is a translation of the basic key-feel from the client: bold, unique, imagination, abstract, and modern look. We take the frog-eye angle of viewing a flying aircraft as the shape inspiring the 'X'; and stealing some graphic features from the Jurassic bird Pterodactyl image to trigger some crispy uniqueness on the look. Meanwhile, inter-connectivity becomes the basic idea for the development of '55' shape. The elegant curvy lines locking the numbers one to another represent the holistic interlocking process an event-organizer should run through when doing its business.
