With LEGO Digital Designer MINSTORMS mode you have access to hundreds of virtual LEGO MINDSTORMS and Technic elements.
LEGO Digital Designer MINDSTORMS mode includes all of the MINDSTORMS elements that you need, including a virtual NXT Intelligent Brick. Wires are color-coded so that your plans may be clear to all. (NOTE: virtual brick is for construction only, and does currently not contain or emulate NXT software.)
You may build using a wide array of MINSTORMS and Technic elements, or choose to filter your element choices to a specific LEGO set. LDD counts the amount of pieces available to you so that you can challenge yourself to redesign a set!
When you are finished with your amazing creation, you can upload your LEGO Digital Designer file to the NXTLog. Other LEGO MINDSTORMSfans around the world will have access to your instructions to build your cool robot! You can also read comments and feedback. Join the community and share your designs!
The greatest game in the world, it's beyond my words.
LDD is a free-build game you can download off the LEGO website at http://ldd.lego.com/en-us/default.aspx?icmp=COUSCreateShareSL100LDD
