OMSI is an awesome place for kids to get to explore the basics of science and technology. Loved it as a kid, and still do as a grown up. Well older kid really. I was never really fond of their logo, big red block letters with no kerning.
I wanted to design a more colorful and intriguing logo that would reflect what OMSI is about.I think the lime green is a great contrast against the cool gray, and it stands out to kids and reflects that "sciency" feel. And the cool gray reflects the industrial aspect without being overbearing.
