  Video games have emerged as a medium for learning by creating engaging
environments, encouraging creative and deep thinking, and exposing learners to
complex problems. Unfortunately, even though there are increasing examples of
video games for many basic science and engineering concepts, similar efforts
for higher level engineering concepts such as mechanics of materials are still
lacking. Here we present a mesh-free elasticity solver implementation in the
popular video game Minecraft, a sandbox game where players can build any
structure they can imagine. Modifications to the game, called mods in the
Minecraft community, are a common feature of this platform. Our elasticity mod
computes the stress and deformation of arbitrary structures and colors the
blocks with a heat-map to visualize the result of the analysis. We used this
mod in the Honors section of two courses taught at Purdue University: Basic
Mechanics I Statics, Mechanics of Materials. This articles describes our
experience developing and deploying this tool to encourage its use in
biomedical engineering classrooms. A future goal is to engage the broader
audience Minecraft players that already interact regularly with Minecraft mods.
