Holographic art was an art form which had existed prior to the 24th century. One example of this form was the 21st century work Woman in Four Dimensions, which was owned by Lewis Zimmerman as of 2376. Believing his death was imminent, he composed a last will and testament in which he intended to leave his entire collection of holographic art to Reginald Barclay, although his immediate death was averted by The Doctor.
