It's an Arduino cake for party 
LOL
Why does pin 13 not a have a blinking LED?
Brilliant!
Nice!

ah ah ... that's fool 
Do members here get a slice? what does it taste like?
Wafer silicon

You should have put a candle on the power led spot, and one of those novelty blinking candles on pin 13!!
Great cake though.
Oh.
