Virtual Grellman vs X

Virtual Grellman is attribution and educational software designed for large cents. Identifying your large cents by comparing photos instead of text descriptions makes attribution a breeze. Rarity ratings, die pairing information, and die state information is provided for every large cent variety, as well as DRNs (Date Reference Numbers) for the late date varieties. You can also keep track of your large cent collection, which is maintained across devices.

X-ray Scattering Simulator is a mobile application tool for demonstrating radiation scattering virtually. The demonstrated data is based on real life measurements in a hospital environment. The application is based on Augmented Reality technology (AR) that allows the user to add virtual 3D elements to the real-world environment through the camera of the mobile device. The objects in this application are the patient, X-ray machine and a color map depicting the radiation scattering. The purpose of this application is to demonstrate how the radiation generated during the X-ray imaging scatters to the environment.
