For that extra bit of sparkle, how about a Light-up Frame? Here are some examples, including the very popular Christmas boxes. The boxes can either be wall mounted or stand alone.
Each one is available in a black, white or a wood frame and is 23 cm squared. The battery pack is cleverly hidden at the back of the frame and two batteries are provided (they are the small button batteries CR2032).
They can all be personalised and I can, of course, include your beloved pets if needed.
These light up boxes are £30.
