"What better way to remember my final exhibition than by getting a tattoo of the logo?" she asked.
Miss Norgate (20), of Dunedin, is among the first graduates of the polytechnic's communication design course, which takes a practical, media-based approach to design.
To showcase their work, the class created the Enter exhibition, which will run alongside the polytechnic's annual Excite exhibition.
"Dig a Tattoo" completed the piece in time for the opening of the exhibition last night.
The logo is her fourth tattoo, adding to her polytechnic computer log-on and a game of noughts and crosses.
"I like that [exhibition] name . . . I thought it was funny, so I put it on my back."
She got the noughts and crosses tattoo because it was something she always doodled.
Her classmates described her latest tattoo as "very Carmen".
Enter is located in A block of Otago Polytechnic in Forth St.
It will be open from today to November 28 (excluding November 23) between noon and 4pm.
