Graphical User Interface (GUI) is a UI based on graphics, such as icons and pictures and menus, instead of text; and uses a mouse and keyboard as input device. Creating graphics, icons and menu etc from scratch is not an easy task and is quite time consuming too. In this fast world, a designer cannot afford to spare time for creating these if one wants to meet the deadlines. So this is where ready-made GUI templates come in handy.

GUI templates are loved by designers and are always in demand because of the fact that they are extremely easy to use and can be customized according to your needs. Designers are thus always interesting in finding some good GUI resources. These are perfect for making web and mobile mockups easily and quickly, thus saving a lot of effort and time of the designer.
