Allowing your kids to scribble everywhere they go is a good idea, it trains them to be creative and probably be able to write properly earlier, however, encouraging them to draw on the wall with a virtual pen is probably not such a good idea. The KLEXL virtual pen is actually a projector that comes with “pens” equipped with sensors. When light is projected onto the wall, kids can use the pens to “draw” on the lighted area and “virtual” images will appear. Removing the drawings is just as easy as turning the projector off but before you go running to get one, please throw away all your permanent markers, pens and pencils because if they get their hands onto something that can draw, your wall will be needing a whole new makeover because they’ve been trained to scribble on the wall!
