Portal Cosplay at Gaming Convention

A person dressed in a white bodysuit with black accents, holding a prop from the popular video game Portal. The individual's outfit features a logo on the chest that reads 'APERTURE SCIENCE HANDS-ON UNPLUGGED DEMO' and includes various markings resembling circuitry or wires. They have short blonde hair styled in a bob, parted to one side, and are wearing black ankle boots with white socks. Their face is painted white with black lines drawn on their cheeks, giving them an otherworldly appearance. The prop held by the person appears to be a modified portal gun from the game, which they hold at waist level. In the background, there is a crowd of people visible through a glass wall or window, although they are not in focus. The overall atmosphere suggests that this image was taken during a gaming convention or similar event.
