Link straight to todays challenge: http://alphalupi.bungie.net/?day=2 If you're looking for a way to help - log into the above link and keep refreshing every 5 mins (that's how often the server checks). By being logged in during any 5 minute span you add a white dot to the right image - the more white dots the faster we solve this - but your white dot will only last for five minutes (that's why you need to keep refreshing). You'll be able to see the fruits of your refreshes in realtime here (it gets re-uploaded every five minutes): https://www.dropbox.com/s/9a9a1eec15fgwrf/finalMaskedOutput.png Each 5 mins you log in puts a dot in a different location - if your white dot falls on a space we haven't filled in yet on the final image that information will automatically get added to the final Output at the above link. Where the location of your white dot will land is a combination of the time of day and your location on earth. So get others involved to get other locations and keep refreshing to update yours with time.
