They're calling it the "eBody project" but it remains to be seen what shoppers on Dublin's O'Connell Street will make of it.
For one week, 24 hours a day, Padraidh Hearns, a former Mr Ireland, will live, eat, drink and sleep in Clery's department store window.
His task is to survive the week armed solely with a mobile phone and an Internet connection. Organisers say Hearns will be forced to use technology to survive, "ordering his food and essential items online".
His trial begins on April 26th as part of eWeek, a week-long programme to showcase Irish technology organised by the Dublin Chamber of Commerce.
Spokesperson for eWeek Ms Gina Quinn said: "The purpose of the 'ebody' project is to demonstrate how much can actually be achieved through the use of simple technology."
Ms Quinn said: "I'm hoping that we'll all learn something new from Padraidh's experiences!"
"I encourage everybody to come down and see eBody in Clery's window and also to visit free exhibitions and interactive demonstrations during the week."
The Dublin Chamber of Commerce says it is expecting up to 10,000 people to attend over 50 events at the Mansion House, Digital Depot, Civic Offices and several other locations.
