Hi,
Not sure if anyone has seen the Lego Ideas Crowd Sourcing initiative. I recently built and posted a radio-controlled jumping frog:
https://ideas.lego.com/projects/65239Legos are a great tool for protoyping shape and design, and even mechanical movements. Has anyone else used Legos for prototyping animal toy designs?
Anyone interested in Lego Ideas, I recommend you submit your own creations and vote for those you want to support, including my jumping frog

Best,
Tom
