The Kickstarter's halfway through, so what are you going to do?

JABBERWACKY
‘Twas brillig, and the slithy toves Did gyre and gimble in the wabe: All mimsy were the borogoves, And the mome raths outgrabe.
“Now back the Kickstarter, my son! The wondrous books, the cards, the dice! Beware of missing out, and shun Mere trifles – don’t think twice!”
He took his credit card in hand: Long time the right reward he sought – So rested he, on Tweedledee, “An eBook’s fine,” he thought.
And, as in uffish thought he stood, The Jabberwock, with eyes of flame, Came whiffling through the tulgey wood, And burbled as it came!
“You want a hardback,” quoth the beast, “The art’s done by Kev Crossley. And while you’re there, I do declare, A signed one’s not too costly.”
One two! One two! And through and through The frantic mouse went click-‘n’-clack! He used his smarts – picked Queen of Hearts – And went galumphing back.
“And hast thou backed the Kickstarter? Come to my arms, my beamish boy! Oh frabjous day! Callooh! Callay!” He chortled in his joy.
‘Twas brillig, and the slithy toves Did gyre and gimble on the knoll. Now go pledge your support in droves, And help us reach our goal.
