Geowood is made using only the seven shapes shown above. To make it more of a design challenge none of the shapes have been scaled.
Use the uppercase if you want something chunky. Use the lowercase if you want something a little bit illegible and quirky. It has numbers but it doesn't have any punctuation, so I wouldn't recommend it the body copy font of your next book.
Please be aware that you may need to adjust the kerning, some of it is not perfect.
