I’ve always wanted to know how to project “stencils” on walls or sidewalks, as a lot of clubs or businesses have started to do. After a lot of knowledge from the Chicago New Media list, I found out that these projectors are called gobo projectors. I also found out that IKEA sold an inexpensive version of such a projector called Isbrytare. Jim Dennewill has a good rundown of the projector.
My impression is that IKEA no longer makes this product. I’m wondering if there are any other ~$40 projectors that are currently in production.
