Another nice thing about the Alpha Clock Five is the Serial protocol that allow you to control all aspects of the clock.
The software is really polished, no flickering display, nice gradient while dimming, user definable characters. The only thing missing you could possibly want is different intensities per segment.

Support for debugging a running microcontroller has been available for competing developer kits for a while now :
- NXP has it for the many LPCXpresso boards,
- some developer boards have a Segger J-Link on board.
- The TI evaluation kits like the Tiva Launchpad have and "On-board In-Circuit Debug Interface (ICDI)" which is more or less open.
- Some Freescale boards have OpenSDA.
- The ST NUCLEO-F401RE uses ST-LINK
I'm curious how Arduino.cc will integrate the debugger in the Arduino IDE.
