And that, children, is why Geometry is important and useful in the "real world". Now, go finish your homework.
Anyone else setting up hexayurts at Flipside this year? Look for me at Waterloo or PETs HQ and come say Hi! I'm always interested in seeing other's structures, especially if they stray from the Vanilla variety. I'll show you mine, if you show me yours :o) *mew* mu/gwen (PETs Lead) On 14 May 2010 20:02, chakra/david from golden cafe <[email protected]>wrote: > Good comments Percy. > > No, I haven't used sketchup.
