The Tinder-O-Matic
The Tinder-O-Matic can ‘like’ a new profile every 4 seconds or so, which averages to around 900 likes per hour. If left on for 12 hours, the Tinder-O-Matic will like over 10,000 profiles!
Tinder-O-MaticAfter building the InMoov finger starter, I found that it was spending a lot of time sitting on my desk. I decided to put it to use, and the Tinder-O-Matic was born. 
Tinder is a matchmaking app that uses a picture, a short bio, and location info to find potential dates in a predetermined radius. If you ‘like’ another user, and they ‘like’ you back, both users are sent a notification, effectively breaking the ice and leading to a conversation.
Obviously, the best (and intended) way to use the app is to read someones profile and see if you share any common interests or hobbies. In the interest of conducting an exhaustively comprehensive search, I built a machine that will tirelessly ‘like’ every single user in a predetermined radius.

I’m sure you came up with this without seeing it, but the artist Tully Arnot has made something like this using a silicon moulded finger:
How does the finger actually activate the capacitive touch screen? Is there a metal contact on the finger tip connected to ground? It would be awesome if you could show the complete circuit you use.
It’s just a phone stylus. it doesn’t require any external grounding, etc. The stylus has a rubber tip that is impregnated with a capacitive material.
