I currently use a Chessex Dice Boot for rolling dice at the table. It's fairly compact, very portable, and does a great job of minimizing the table area required for a good roll of the dice.
There's one slight down-side to this device however. It's noisy. The sound created by a die as it bounces between the plastic landings is significantly louder than that which is normally made by rolling it on the table. While we all do love to hear our dice roll, this can be especially disruptive in certain environments.
So, I'm seeking a way to modify the Boot so that the rolls are quieter, while hopefully preserving its portability and ease of setup/teardown. Alternatively, does anyone know of a site with instructions for Do-It-Yourself dice tower construction templates and "How-To"s that take the noise factor into account?
