Here's the rough parts list from the blog;
Arduino Mini Pro USB-Serial converter 12x TLC5940PWP (SMD) Led drivers 60x RGB SMD LEDs DS1307 + battery to keep track of time Loads of circuitboards (12 black ones and 60 white ones)
Obviously, we'll need something more concrete for construction of one of these. I wonder if we can use an Arduino Nano to replace the first 2 items. We could do a custom shield to hold the DS1307 and a small battery for backup power, and connectors for LEDs
Construction Notes: The ring of LED bezel's appear to be separate. If we try to use one or several pieces of plastic (acrylic?) to avoid having 60 separate blocks, I think we'd end up "bleeding" too much light to adjacent positions. It might cut costs to avoid all of the connectors that were used. It makes it harder to service, but these things really shouldn't wear out.
Parts details;
TLC5940PWP - LED driver - http://focus.ti.com/docs/prod/folders/print/tlc5940.html (samples ordered) driver library: [2]
DS1307 - real-time clock - http://www.maxim-ic.com/datasheet/index.mvp/id/2688 (samples ordered) - helpful [3]
Tri-color LED - http://www.sparkfun.com/commerce/product_info.php?products_id=105 or http://www.sparkfun.com/commerce/product_info.php?products_id=7844
Arduino Nano - instead of Pro Mini bc. includes USB - http://www.robotshop.com/arduino-nan-v-3-4.html

Notes:
11/12/10 - received 3 samples of the LED driver in DIP package. should be easy to bread-board an develop the display portion
