Every week, Darragh Doyle – a man who knows his way around the Internet – joins Sean Moncrieff live in studio to fill him in on all the most useful and uselessly amusing apps and sites he's found making his rounds online in the last secen days. 

Here's what Darragh covered today...

• An opening video

Ethan Zachery Scott, a colourblind man, is overwhelmed when he sees purple first time after someone gives him a pair of special EnChroma glasses with corrective lenses.

• Vivino - never pick another bad wine
  

Take a photo of any wine label and instantly learn that wine's rating, reviews, and average price. All supplied by the world’s largest wine community of 10 million wine drinkers.

• Beme 
  

Described as the simplest and most authentic way to share your experience on video. Pronounced "beam," the iOS app is a bit like Snapchat but without the ability for retakes.

•  Project Alexandria
  

When you finish a book, do you want another just like it? If you’re not a kindle reader, it’s sometimes more difficult to find something recommended for you. Enter Project Alexandria, a book exploration engine.

• How How do you sleep, compared to 27 of the world’s most creative minds?
  

If you’re worried about your sleeping habits and think “that might be why I’m not creative,” you can compare and contrast now.

• The Nostalgia Machine 

Anyone who loves music and wondering what was number 1 way back when will live the Nostalgia Machine. Compiled from the Billboard Year-End top 100 singles, it complies music videos from 1960 to 2013.

• Why Time Flies 
  

Maximillian Kierner has made an extraordinary website that shows you why time flies the older you get. A really good way of explaining to people who might not understand it.

• 7 Cups of Tea
  

@darraghdoyle @NewstalkFM http://t.co/gm6ChjEPBJ I have to say this. It's not mine but it's wonderful

7 Cups of Tea is an on-demand emotional health and well-being service. Their bridging technology lets you connect one-on-one to a listener while remaining completely anonymous.

• Google Sheep View 

Very simply - where do sheep appear on Google Street View? Here’s a website that answers that...

• And finally...

A lot of people seem to be videoing and sharing the joke “30 cows in a field. 28 chickens. How many didn’t?” Seánagh Rice is having a bit of a problem getting this one.
