Some information we require permanent visible such as the date or the time. Depending on what you are doing it might be required to have other informations like the weather or the time in other places of the world etc.
This information can be displayed on your PC screen but as this is not really the best possibility from various reasons I made some time a go a Desktop Widget ( http://www.thingiverse.com/thing:857858). As the display capacity is very limited I made now a bigger one: While the first was in a clear rounded appearance I tried with the new one to stay in clear simple shapes but was looking for sharp edges and hard lines in order to give a hard, clear, definite appearance.
Of course it can be used as just as an other weather display but I require the exchange rate and the time in different cities of the world at my fingertips.
