Stasis cube

A stasis cube was a form of Time Lord art found on Gallifrey, which the Eleventh Doctor described as a "little sliver of time" held in perfect stasis in a frame that was bigger on the inside than the outside, similar to transdimensional engineering. The result, according to Clara Oswald, resembled a 3D oil painting. It was possible for living beings to exist in these environments.
In the early 21st century, several stasis cube paintings, including one titled Gallifrey Falls No More, were in the collection of dangerous art housed in the Under Gallery of the National Gallery in London, where figures disappeared from the pictures and the glass over the cubes shattered. It was soon revealed that the figures were Zygons, who had used the stasis cubes to freeze themselves in 1562 and wait until the planet was more technologically advanced. This led to a meeting between multiple incarnations of the Doctor — the Tenth Doctor, the Eleventh Doctor, and the incarnation who fought in the Time War.
Using the method of implanting themselves in stasis cube paintings the Zygons had been using, the Doctors froze themselves in the Gallifrey Falls No More painting in order to access UNIT's Black Archive in the Tower of London, which was TARDIS-proof, and avert the destruction of London by self-destruct during a showdown between the Zygons and Kate Stewart. The War Doctor likened Gallifrey's preservation in a pocket universe to be, "like a painting", referring to the stasis cubes. (TV: The Day of the Doctor)
A Time Lord author compared the stasis cubes to a more advanced form of miniscope, something he considered quite ironic given how his species had championed an inter-galactic ban on the alien technology. When reflecting on how stasis cube technology had been used to save Gallifrey after the Last Great Time War, the author noted that restoring the planet to N-Space had been as simple as walking out of a painting once the Siege of Trenzalore had allowed them to determine which of the nearby universes was theirs.
