Don't you hate it when you submit a form and then there's an error and it sends you back to the form with all the form fields blank? Especially when you've written a whole bunch in one of them? Yeah, I hate that too. This is a 3d illustration/interpretation of a city from Calvino's Invisible Cities. Thekla is a city that is forever under construction "so that its destruction cannot begin." According to the inhabitants the blueprint for the city is the stars. Everything is modeled in Maya, then stuck into the Blender 3d game engine. Like the city, the walkthrough is unfinished. This is due to problems with stability and, frankly, bad program design for blender's 3d engine and textures and lighting. I didn't have time to add collision or to make it possible to walk up the ladders and explore the second floor as originally planned. Nevertheless, there are playable versions online: Windows version Linux version Use arrows to move, page up to look up, page down to look down. Disclaimer: I make no guarantees that these will work. At all. Probably the sound won't work on linux because of a blender bug, anyway. They may make your video card explode. The ambient hammering sound came from the free sound project: http://freesound.iua.upf.edu/samplesViewSingle.php?id=25060
