Mold making demo?

I have noticed that a lot of people are making physical games for this class. Coming from a sculpture background it is no secret that I love to make things!! If you guys need any help protoyping or making physical objects for your game I would love to be of assistance. Also Arturo I was wondering if it would be beneficial to the class to give a brief demo on mold-making and casting? If anyone would be interested in this please let me know.
