Create. Educate. Impact.


The soul of these products is idealistic, optimistic and rooted in the belief that imagination is an essential part of childhood. They are never gender specific, and encourage an exploratory, unstructured play.



Cas was in the process of making gifts for her collaborators at Friends of the High Line when Areaware called up looking for new products. They saw the prototypes in Cas’ studio and convinced her to develop them as products instead. Inspired largely by building blocks (no surprise in Cas’ case) and the curious, chunky characters found in geometric shapes, Bird Mill invites playful interaction. A beautiful blending of toy and industrial languages inspired by the Italian Memphis movement.  Click here for more info.



Geemo was invented while Cas was pursuing her MFA at Cranbrook, and launched at the NY MoMA Design Store in 2007.

It has since won numerous awards and shown in design and toy fairs in Moscow, Tokyo, Seoul, New York, Hamburg and Riyadh, Saudi Arabia.

Sold in Geemanisms of 5, Geemo’s flexible magnetic limbs grab and repel each other in unpredictable ways. As Geemo comes to life in your hands, you can build, discover, create, and imagine with this new species of toy. Cas worked with factories in the US, China and ultimately Japan to bring Geemo to the market.

Geemo is currently manufactured in a small factory in Tokyo. Utility patent awarded 2010.



Rigamajig is a large-scale building kit for hands-on free play and learning. The collection of wooden planks, wheels, pulleys, nuts, bolts and rope allows children to follow their curiosity through play.

Conceived and designed as a custom play feature for the High Line Park in New York City, the Rigamajig was developed by Cas Holman and Friends of the High Line in collaboration with Early Learning Educators, Woodworkers and Children. It was launched in 2011 as the High Line Children’s Workyard Kit and reflects the High Line’s industrial history, simple, honest materiality, and the organization’s dedication to creating meaningful play opportunities for children and families.

Since its debut, the Rigamajig has found its way into numerous schools, playgrounds, children’s museums, and backyards. The award-winning design is evolving and expanding as we learn from our pilot schools and playful friends.

National non-profit KaBOOM! has partnered with Heroes Will Rise to help give kids the childhood they deserve by bringing play to those who need it most. Rigamajig is an ideal solution for all communities because it provides easily accessible, cognitively challenging play opportunities for children of any age in any environment. This partnership will allow KaBOOM! to promote active play in more communities across the nation so that we can give all children the opportunity to become happy, healthy, and successful adults.  Visit the Rigamajig website for more info.


Cas Holman has spent the last ten years immersed play, education and imagination. Through her company Heroes Will Rise, she designs and manufactures tools for the imagination. These materials are manipulable parts and pieces which inspire constructive play, imaginative forms, and cooperative interactions between people. Abstract in their identity, these tool/toys inspire children and adults to imagine the origin and story of the toy as well as how to use it.  “What is it?” and “What does it do?” are answered in intuitive details, play prompts, and semiotic clues, making the instructions implicit in the tool/toy.

She is a full time faculty at RISD in the Industrial Design Department and recently relocated from Brooklyn to Hope, RI where she prototypes her playthings on five acres known as Camp Fun.

Cas is the founder and principal designer at Heroes Will Rise.  Heroes Will Rise is an independent toy company focusing on products designed in the spirit of invention and creativity. The soul of these products is idealistic, optimistic and rooted in the belief that imagination is an essential part of childhood. Our toys are never gender specific, and encourage an exploratory, unstructured play. Their Hope, Rhode Island workshop is situated on a retired summer camp filled with toys, drawings, prototype structures, dreams and dogs.
