We produced this animation for the undisputed Indie gods of rock They Might be Giants! Check out the herky jerky awesomeness of "This Microphone." Character Design and Direction: Joyce Hesselberth & David Plunkert. Animation by Joyce Hesselberth & Brianna Gooch.

I love what can be done with a simple animated .gif file. 

This is the book trailer for my new book Shape Shift, published by Henry Holt in 2016.

This animation, titled Securing Rights, Combating Climate Change analyzes the growing body of evidence linking community forest rights with healthier forests and lower carbon dioxide (CO2) emissions from deforestation and forest degradation. 

Our latest app, PrestoBingo Colors provides an introduction to colors for kids from preschool age on up! Kids wander through robot factories and butterfly fields as they master the intricacies of color identification. Basic colors like red, yellow and blue are mastered first, but then kids can move to intermediate colors like magenta, gold and turquoise. Finally, in the advanced mode they can tackle crimson, ochre, cobalt and many more – over 80 colors in all! 

PrestoBingo Color’s first set of colors covers basic identification for preschoolers: black, blue, brown, gray, green, orange, pink, purple, red, white and yellow. On each screen, kids are asked to find objects of a certain color. Friendly narration guides them if they get stuck. To make it more challenging, sometimes kids will need to tilt their device to find a hiding shape that’s just off the screen. Then, when the basics are mastered, the difficulty level can be changed. Magenta? Periwinkle? Plum? Developing a broad vocabulary to describe color becomes a fun game.


  • Beginning, intermediate and advanced color levels
  • Over 80 color names to learn
  • Friendly narration to guide your child through the app
  • Animations and physics-based interactions

PrestoBingo Shapes provides an introduction to geometry for children. Circles, diamonds, ovals, rectangles, semicircles, squares, triangles, trapezoids, and triangles are explained and identified. Each screen presents a different shape-finding puzzle and kids are verbally and visually prompted to click on the shapes. Animations throughout the app explain geometric forms concisely, and encourage children to see shapes in a unique way. When prompted for more information, shapes are described in terms that young kids can understand, "A trapezoid is a triangle with the top cut off. It can be a tent in the woods, or a lampshade, or a ship sailing away."


  • 16 Illustrated puzzles
  • 25 animations
  • Concise descriptions of shapes in terms kids can understand
  • Text based, verbal and visual prompts throughout
  • A narrator to guide your child through the app
