Dinesh at beyondrelational.com has a detailed post on creating a basic Silverlight application using Microsoft Visual Studio 2010. Microsoft has shown a huge commitment to Silverlight and though most developers will be well aware of it I think there is still a lot of value in pointing to basic tutorials for students or professionals who are not yet actually involved in programming applications with it. Redmond has an outstanding tool in Silverlight and if you would like to help yourself stay relevant in the business in the future you would do well to educate yourself on this part of the Microsoft Visual Studio 2010 suite.
Digital Sculpting Tool
Digital Media Minute has done posts before on tools for making 3-D art including a slick 3D character creator, but take a look at Sculptris, a really impressive, free digital sculpting tool or 3-D modeler that you can use to make incredibly detailed and organic-looking 3-D figures. If you have ever wondered how the incredible figures that you see in video games and other places are created, take a look at this piece of software. I think that a fairly untapped market is to sell to people who might be interested in 3-D sculpture just for the sake of making cool models in 3-D without any further application necessarily. For Mac, Windows, Linux.
