From the arduino IDE select the tools menu Tools->Board and scroll down and find ATtiny 24/44/84
Then again click on Tools menu and select ATtiny84 from the Chip option
Click on Tools and then select Clockwise from the Pin mapping option
Select the oscillator speed 8Mhz Internal from Tools->Clock
Click on Verify to verify that the sketch compiles without errors

Pick up the Arduino UNO you programmed earlier and wire it with the ATtiny84 chip from the spinner from this diagram
From Tools->Programmer select Arduino as ISP
From Tools->Port select the port of the Arduino UNO connected to your PC
Hit the upload button from the Arduino IDE. The upload process to the ATtiny84 should take 10 seconds.

You can change the text and shapes of your spinner from the textAndShapes.h header file

You can use any Arduino board to program the ATtiny84, just google for Arduino [UNO/MEGA] etc.. as a programmer
