Laptopograms: Contact prints from your computer

This looks like fun- this maker has been using the light from a laptop screen to expose photographic paper, creating what they call a laptopogram:

Laptopograms are images made by pressing photosensitive paper onto a laptop screen and flashing an image in a manner not unlike contact printing or photograms. The name ‘laptopogram’ is a misnomer – I reckon they can be made with pretty much any monitor. Perhaps ‘Luminous Screen Emulsion Transfers’ is a better name. Here, however, the negative is a digital image – and is flashed for a little time onto the paper before developing the image in a darkroom.

These prints were made with an IBM R51 Thinkpad running Lucid Lynx with a resolution of 1024 x 768 pixels. All prints were developed on Ilford Ilfospeeed RC Deluxe 5 Glossy paper using Tetenal Neofin Blau with water as a stop bath and a fixer of unknown provenance.

One of the best parts is the code to control the shutter:

vbetool dpms on ; sleep 2.0; sudo vbetool dpms off

If the contrast ratio could be made high enough, this technique would be great for directly exposing circuit boards or screen printing masks! Anyone know if this is at all possible?
