TI-89 Bitcoin Diceware Tool Released

Matt Whitlock has recently released a diceware tool for generating Bitcoin address and private key pairs on the venerable Texas Instruments TI-89 portable general purpose portable computer commonly marketed as a "graphing calculator." The software takes input derived from analog dice rolls. The source code, written in C, is available here and it compiles with TIGCC. Whitlock previously worked on the Lamassu Bitcoin ATM. A video where Whitlock demonstrates the key generation process at 10x speed is embedded below:
