Logo restyle

[GioBonvi]

I think the current logo could really benefit from a redesign: if anyone wants to give it a try please do so! It's not necessary to open a PR for every proposal, just link the image in an answer to this issue.

Problems which should be solved:

• currently it's nothing more than a patchwork of icons with conflicting styles and colors
• it uses Google Contact and Google Calendar icons: I am not sure what copyright laws apply to icons and service logos or if this falls under "fair use". Maybe someone knwoledgeable in this area could shed light on this; in the meantime not using them is probably the best way to go
• it's a raster image: as pointed out in [ImgBot] optimizes images #129 it would be great to have it as a vector image

Guidelines:

• if you do not know what this script does you can give a quick read to the homepage.
  Alternatively this is a TL;DR: GoogleContactsEventsNotifier is a script built on the Google Script platform which lets you receive notifications for your contacts' events (birthdays, anniversaries and custom events). It collects data from your event Calendar, from your Contacts and from Google+ profiles to build a customized email notification which sums up upcoming birthdays and events.
• feel free to completely change the structure, dimensions, format and style of the logo: when I put it together I wanted to convey the idea of a service that uses Calendar, Contacts and Gmail to get you those notifications, however I'd love to see any alternative ideas
• a little note regarding Google+: I did not include it in the logo because at the time it was not integrated in the script nor did I plan to integrate it. However, as explained in Google+ is being shut down #131, Google+ is going to close in the next 10 months, so I'd say including it in the new logo is not worth it anyway even if you want to keep the "service aggregation" theme

Thank you in advance to anyone who wants to give a shot at this!

@GioBonvi I would like to present these three proposals of logo for your project all oriented to represent the sending of electronic mail related to calendar events, I hope you like it and if you want some change with pleasure I can do it

The balloon is supposed to represent events, such as birthday parties for example.

This is my attempt at the vector version :
