A quick idea for an item which would be useful in the lab to assist with cost savings on upkeep and also an Imaginem specialisation.
Libram of Imaginary Pages
(Lesser enchanted device: Cr/Mu/Re/Im 30)
The libram appears to be a piece of treated oak carved to look like a very small closed notebook. Upon command the libram will create an illusory sheet of writing paper, which can be used to scribe notes. Created as a level 25 spell effect, modified for +5 levels to allow 24 uses per day.
An Imaginary Page
Creo Imagonem / Muto / Rego 25, R: Touch, D: Moon, T: Individual
The virtual paper includes a tactile illusion so that slight resistance is felt by the writer when being changed. When written upon the illusion reacts to the motions of the writing implement, so that ink is not needed to write on the surface.
The illusory pages can be moved about or placed in mid air, and altered as pleases the writers just like a normal piece of paper. The illusory pages can be created in three sizes: note/palm sized, large book sized, and table sized.
(CrIm base 2 for visual and tactile illusion, +1 Touch, +3 Moon, +1 can be moved around, +1 intricate text and drawings, +1 changeable image)
