Make a valuable and intangible service (the work being done by the mechanics) more tangible.
Have time lapse cameras situated at work stations in the place where the mechanics service cars. The software allows you to start recording of a time lapse sequence at a particular service station, and stop it when finished. You then immediately send the customer (even before they pay and receive their car back) a link to the video file.
To see how something changes over time and from all sides.
A device you place around the object you want to photograph, and that moves around it at a pace you control. You put your smartphone into the device, set the time lapse parameters (time, pace, movement tempo, etc.) in the app, and the device will move the smartphone around the object taking photographs from all angles, by the parameters you set.
