Unfortunately this campaign is likely not going to meet its challenge but nevertheless is a clever product that may spark some ideas:
You probably know, that you can build a simple projector from nothing but a light, a simple transparency and a camera lens. All you need is the right connector, and GuerillaBeam is just that.
– totally modular, allowing the the use of any lens and any light
– portable, by using high powered flashlights (standard configuration)
– most affordable, since it doesn’t need any expensive components
– eco-friendly: Get it digitally and print it at your place
Open Source, at least with you help :-)
