How about just getting a family picture and playing around with the picture adding effects (if your not that creative and dont know how try any mosawer or theres a place in Galleria 2000 who plays around with pictures professionaly) oo place it in a picture frame with flowers and chocolates.
Chocolates:

If your mom is into creativity and you have plenty of time on your hands why dont you make her a scrap book of family pictures and each member of your family could comment on each page underneath the pictures and good memories.
