Some impressive hacks resulted from Dwolla‘s second internal hackathon at its headquarters in downtown Des Moines, Iowa, the company announced on Friday.

Two of the more notable hacks were a Dwolla-based rewards program and a Dwolla mobile point-of-sale app.

Dwolla offers a digital payment and money transfer service that is free for transfers for under $10, and just $0.25 for transfer of more than $10.

The event gathered Dwolla employees from across the country for a two-day event featuring eating, drinking, and a lot of music. Oh yeah, and some coding.

Here are just a few of the many products coming out of the hackathon:

Dwolla Rewards: Earn rewards when you make Dwolla purchases, and use those points to cash in on some sweet deals.

Flashy Map: A map that shows Dwolla transactions moving from one place to another, as shown on a map of the United States.

Dwerchant + Printer: While these two hacks were separate, together they make one mean point-of-sale app. Easily request Dwolla payment from customers that walk into your store, using blue tooth technology. When they fulfill their payment, a traditional receipt is printed out.

These are three hacks with potential real-world applications, but there are not explicit plans to build them out and implement them. The hacks from the event that may see further development are being kept secret at this point. One of the hacks that probably will not make its way into Dwolla’s codebase anytime soon:

Skull Light: When code is committed, a lamp light flips on. If the code is bad, a red skull lamp lights up.

And we can’t leave out this gem from the company’s first internal hackathon over the summer:

Kegbot: The Kegbot integrates with a tablet that will use a flow meter to monitor the amount of beer that each employee pulls from the tap. When the keg is dry, Kegbot will divide the price of a new keg according to the amount of beer consumed by each individual, and send out payment requests via Dwolla.

Silicon Prairie is so hot right now.
