NASA Ares I SC includes alpha files (3D models, textures, documentation, configuration files powered by Vinka's generic dlls) for integration (files + future custom dll coding) with Franz Berner (aka Francisdrake) CEV-Orion addon (20070505 edit: please see the end of this description for an updated link to Franz Berner's CEV-Orion / site).
Despite this is a kind of updated development package about the SRB launcher (VSE's CLV, as per current plans), I believe that fellow orbinauts might also have a bit of fun with these files (while Franz codes the custom dll) and that was one of the reasons why uploaded the zip.
To read this addon's documentation (Introduction, Install and Uninstall notes, List of Files, Ares I description, Performance Data, Flight Manual, "Legal Stuff", Credits, Thanks and Feedback notes) please search for the following path in the zip structure:
