Check out this great video (in Spanish) about a “Calcuino” project from Opiron Electronics built using one of our 2.8″ TFT Touch Shield for Arduino, and tuned up on the Adafruit Forums here. Here’s their project announcement at Opiron.com:

Addition / subtraction / multiplication / division and RESET button and DELETE button.
