A study-help puzzle computer game ironically not made for engineers, but with with artists and biology students in mind.
There are two modes; skeleton and muscular. And ideally as many species as possible available at launch, with more added as requested/curriculum dictates. The game will also try to accommodate as many of the main learning types as possible, using reading, writing, listening, and repetition.

In the beginning the player selects their mode and species, and then is presented with the appropriate labeled diagram. They can click on the labels to hear the name of the bone/muscle group spoken, and they are also highlighted in different colours. After they select to continue, the labels are taken away and scrambled into a pool of names that the player must click and drag back to their original positions. If a name is dragged to its correct place its audio clip is repeated and it regains its colour.

The following levels cement this using different methods and a decreasing level of guidance. For one of the advanced muscular structure levels, the player has to type out a name and then click and drag on the skeleton diagram to indicate where that muscle starts and ends. Only if both are correct do they get the positive response of audio, the picture of the muscle revealing and in its associated colour.
