The site is the work of 3form, and as such looks as clean and fresh (and usable!) as their other work – some of the colours are very hard to decipher (the white on yellow that represents ART, for example), but I’m guessing that was a marketing rather than design lead.
It remains to see whether this will take off, and events listing sites are dependant on keeping up to date – but despite not having full details of Artsfest (too much to hope, we’ve been looking everywhere!) it seems already well-stocked. To add your own event you need to email them rather that add it yourself – so let’s hope that they let events of every size, and organiser through regardless of perceived cultural worth.
