lilill - lilill is a Little OS X Application that makes using menubar extras fun. It is optimized for use on laptops, especially the 12" & 13" models where menubar extra space is at a premium. We believe in using menubar extras, and are frustrated when we can't see them all due to limited horizontal screen space and overly aggressive menus in applications. When you make lilill the active application, all you see is its name. No help menu, no edit or window menus. Just a simple thin name with TONS of space to see all those previously hidden menubar extras.
ChunkLove.com - Chunk Love is a site to find steep discounts on Amazon. It's not a site to search Amazon for what you want while mobile, it is to find the things you didn't know you needed that you don't need to pay very much for. It is optimized for users with smaller than normal amounts of screen real estate. You can search for items that are 60%, 70%, 80%, 90% and more off of MSRP. You can also search by category. This is one of few web applications that are also optimized for the iPhone.
