Blinking LED and "Hello, World"

In the software world, it's customary to write a program that prints out "Hello, World" when trying out a new language.  With microcontrollers, the rough equivalent seems to be a blinking LED, as many development boards come with such a sample app.

As a warm-up exercise to getting back into hardware, I thought I'd combine these two ideas, and have a 4-digit 7-segment LED blink "Hola" (conveniently 4 characters long).

For now, there is some visible flickering.  The 'A' in "Hola" is also partially hidden due to messy wiring.

Parts:

1. TI Launchpad MSP430 Development Board
   
2. 4-digit LED
   
3. Small Breadboard
   
4. Ribbon cable with female ends
   
5. 3-pin cable (2 wires used for Vcc/Gnd, 1 unused)
6. Male headers
