Where the Penguins Thrive

sigma star gmbh is an IT‑consulting and training company that specializes in Linux, open‑source software, and cryptography. Their visual language needs to balance the seriousness of the work with the light‑hearted vibe of a team that’s always ready for a joke. The penguin characters are inspired by the Linux mascot, but are a little more motivated and active than good old Tux. They act as stand‑ins for the company’s experts, adding a touch of playfulness to a technically heavy field. To keep the look clean and instantly recognizable, the palette has reduced to black plus the company’s signature red. You’ll find the penguins on presentation slides, coffee cups, stickers, and on LinkedIn, where they pop up with handy tips and insights.
