I always forget how to do round cornered triangles in illustrator but it really is very simple.
Create a normal sharp edged triangle
Go to effect > stylize > round corners
Go to object > path > expand appearance
Easy!
I'm sad that the amazing London Olympics are now over but there is a neat little scrolling website made by "Never Bland" that highlights some of the fantastic achievements over the summer with some cute animations. Watch out for the Queen parachuting in and Jessica Ennis's 6 pack.
Well done Team GB
