This is a really weirdly looking gadget and its functions are also very weird. However I think that it is a very cool idea to project the SMS message on the wall. This is a Guerilla projector from Troikart Company.
I think that this idea of projecting SMS messages on different surfaces is getting more and more popular. So this company has created such gadget for people like me.
It is a rare technique however it has been used before. Nokia phones could do the same thing. So it is not a new idea: they are just developing new ways of doing that.
This gadget looks like a flashlight, but a very sophisticated one. On its side it has a cell phone unit built in. You can press buttons and make it show you the SMS's so you can use it just like a regular cell phone.
