Following is a contemporary Ukrainian Orthodox icon of the confession of Thomas by Ulyana Tomkevych.

Orthodox Icons are not drawings or creations of imagination. They are in fact writings of things not of this world. Icons can represent our Lord Jesus Christ, the Virgin Mary, and the Saints. They can also represent the Holy Trinity, Angels, the Heavenly hosts, and even events. Orthodox icons, unlike Western pictures, change the perspective and form of the image so that it is not naturalistic. This is done so that we can look beyond appearances of the world, and instead look to the spiritual truth of the holy person or event. (Source )
