From cartoon characters to celebrities faces and misspelled sayings, there are some strange tattoos out there. But one man may have made it to the top of the list.

Artist Anthony Antonellis barely winced as a Brooklyn body modification specialist cut open the skin between his thumb and index finger with a 0.75 inch blade and inserted a small RFID chip.

The RFID chip is the size of a grain of sand and was encased inside of a glass capsule before being placed under Antonellis' flesh.

"I Eternal Sunshine'd that entire hour of my life," Antonellis told Animal New York who filmed the procedure.

So why did Antonellis go through 30 minutes of pain to have a chip inserted in his hand that is completely invisible from the outside?

The chip stores 1KB of data and contains information for a GIF that is readable by cell phones.

"Think of it as a changeable, digital net art tattoo vs. fixed information," Antonellis said.

The GIF is of pixelated rainbow colors and appears on screen when a compatible smartphone is held two centimeters from the chip.
