The SpaceAPI provides information about hackerspaces, like addresses, contact information, or door opening status. One team member maintaining this project approached me and asked if I could design a logo for them. Well, sure! :)
This is the normal version, which can be used in website headers, on stickers, and other merchandise:
There’s also a SVG of this, which can be scaled up for large print sizes, as well as a clean, plain SVG, which does not include the fancy texture, suitable for 3D printing, milling, plotting, and so on.
This is a reduced version, which looks pretty in a square and a circle, and can be used as all kinds of avatars.
And finally, there’s a multi-resolution favicon.
