Imagine a classroom display board covered with useful and interesting information about a particular topic. A typical display might include pieces of pupil writing, art work, key words, photographs and commercial produced posters. Lovely though these displays are, they are static. If you want dynamic, ever changing content on your walls you need to invest in digital signage equipment: an investment that most schools can only realistically afford for the more public parts of the school if at all. And as for incorporating sounds, nice though the idea of a talking wall display is, the reality is that sound travels, is intrusive and hearing the same thing over and over again can be really very irritating!
