Cool T-Shirt Design for an Event

Details about the apparel: Tri-Blend T-Shirt for Men and Women
Content to include on the apparel: Product name, logo, london skyline
Ideas for the visual style: See below
Things to avoid: TechCrunch logo
Preferred colors: Clover green (see website) & white only
Extra notes: Designing a T-Shirt for an upcoming TechCrunch Hackathon in London. My company/product, Clover (www.clover.com) is sponsoring and Developers will be hacking apps for our App Market. T-Shirt will be a souvenir as well as a marketing tool we will wear at the event to attract Developers to hack for us...need something cool!

Some design elements to include:
- Could be front and back
- Use Clover green and white only. T-Shirt will be navy or dark grey
- On the front I would like to include the name Clover and a catchy slogan about hacking, highlighting the "love" in Clover e.g. "Hacking with C[LOVE]R"
- Use our company logo which I can provide after job is accepted
- This is our first Hackathon in London so I would like to include an outline of the London skyline
- Any objects that show up at a Hackathon e.g. headphones. Check Google images for what Hackathons look like
- Include the name, place, date of the event>>> TechCrunch Disrupt Hackathon London December 5th and 6th, 2015
