One Thousand Function Keys
This guy, presses one key, and the universe is changed.
Counting just the key-strips, he's got 16 * 4 + 14 * 2 + 8 * 2 = 108 extra function keys!
the big keyboard is Maltron Keyboard. The trackball is Microsoft Trackball Explorer, sometimes selling on Amazon or ebay for $500 USD. Both are best of the best devices.
The several function key strips are X-keys usb stick [see Programable Keypads] The tablet is a Wacom tablet. [see Drawing Tablet] The round thing above it is its pen holder. (thx to Ibrew)
Though, that many function keys is overkill even for me. Extra 20 would be good enough for me. Also, the function keys need to be easily accessible. Best is for it to be part of the main keyboard, such as Logitech Gaming Keyboards
Normally, a PC keyboard's numberpad keys are excellent extra function keys. Such as Logitech G710+ Keyboard. The numberpad keys gives you 17 extra keys. That's pretty enough for me.

This guys's setup is also interesting, in that i've been thinking of comparative analysis of the Kinesis vs Maltron. The Kinesis is prettier, and Maltron ugly, but i think the Maltron is functionally superior, because it has about 28 extra keys in the middle. Those are your super function keys.
