Infinite tap effects

[Birdbrain]

{strionic resonator} + {intruder alarm} + 2 mana dorks + 1 creature with a {T} ability that untaps artifacts + at least 1 other {T} ability creature

Or, you could use it with the alarm, and a creature that adds mana for each creature you control. And maybe a creature that turns mana into a creature as well

[Birdbrain]

For both, your target is {intruder alarm}s ability

Edit: oh, and for the second one, you might want to turn the resonator into a creature
