Piano Note Familiarisation Tool

I am currently learning to play the piano. One of the things I am struggling with is recognising notes that appear below the staff so I thought I would put this together.Primarily for myself, but  I hope someone else out there finds it useful. 

This is some glorified (well not very much) flash cards.  It randomly generates notes below the staff and you can guess the correct piano key. 

You have the option for just Treble, Bass or Both. 

You can also set a Klaxon warning if you select the wrong note.

Finally there is also the option to show the note names on the piano keys. 

I will be adding more functionality to this; such as Key settings and also flipping it on its head so you can do notes above the staff. I also want to get this working with a MIDI Keyboard.
