Darth Vaper was created by Tntech's iCube alongside the TN Department of Health. Darth Vaper, an augmented reality app, was created to show you the dangers of smoking and vaping on your lungs in comparison to a healthy lung. Instructions: You will need to download and print or view the marker on a separate screen in order to fully use the app. Once you have the marker printed or visible on a separate screen, open the app and press the start button with your phone's camera angled to view the marker. Darth Vaper has a link to the marker inside of the app, however, you can also get the marker from https://ttuicube.com/sites/default/files/Marker_Screen_Test9.jpg
