Don't know about PacMan, but LoveLock made me think of the following.

Make a bracelet that has a pulse sensor and a couple of tiny LEDs, pair it with the iPhone and the further connect it to another iPhone/bracelet combo over the Internet. Use one LED for the owner's pulse, and another - for that of a better half on the other end.

PS. Deluxe version could also show a distance between the bracelets.

I think that one of the most interesting projects is http://groupocracy.org/

this is much better, honest and at the same time, technical take on the process of democratic elections and 4-5 years that follow after elections. Better than what? Better than https://www.votizen.com

I too thought this was the most interesting idea coming out of @ G48 Riga. Granted it is just an idea still but imagine the implications of something like this -- especially in the wake of all the uproar from the Occupy Wall Street movement.

Dont forget http://gateme.com that offers full solution to nightclubs and developed QR payments in garage48.

Guys, you were one of the best competitors! We see, there is still lots of work to do to build up great gameficiation and stuff, but thats what we all have to do! Thanks and wish you good luck developing the project!

Augmented Reality Pacman: http://www.youtube.com/watch?v=CIX6wJ1Wv90

Cool. I think the "Scotland Yard" board game as an augmented reality mobile game would be a great idea also.

This seems dangerous... People are going to walk into cars/people/poles etc

The world is a dangerous place, and fortunately there's nothing anyone can do about that. Risk averse people don't typically realize that avoiding risk and avoiding life are synonymous.

People walk into poles reading Facebook and Twitter on their phones already, as well as doing the same while driving. One day you die anyway.

Maybe I am missing something but lots of these ideas seem pretty poor?

This is not an ideas contest, more about networking and having fun while learning new stuff. All about execution. After events like these people are always hugely motivated and in high moods. Hard to describe it if you have not participated yourself.

Still 2 previous Garage48 hackathon teams have won investments from Seedcamp, the leading startup accelerator in Europe.

If even 1-2 teams from each event become real startups, that´s a big win. If not, people meet others and it often happens they start other projects after the event based on new ideas. Everybody wins.

I played a test of a real-life Capture the Flag game that used your phones for capturing the flag and others.

Your phone would contain a radar with your distance to the flag, and to catch other players you'd tap a tag button on the app.

It was fun, and I could see the potential. There is still plenty of issues with GPS tech but they were doing some fine-tuning using wifi towers / etc.

In this case, you only looked down at your phone to view radar, otherwise you ran as normal, and that's (mostly) safe. :)

They were. During the pitching night I was seriously considering just giving up on it and going home. Ended up joining a university mate.

In the end I got to exercise some skills not often used, so the net gain was about neutral, but if I return for the next time, it will be with my own idea.

Exactly. It seems like it was written for kids. After all, who would run around in the city looking at their mobile phones?
